# Neovim Field Manual
|
||||
|
||||
This is a hands-on guide for this config. It focuses on the shortcuts, motions,
|
||||
and working habits that are most useful day to day.
|
||||
|
||||
Leader is `<Space>`.
|
||||
|
||||
## First Moves
|
||||
|
||||
| Goal | Keys | Notes |
|
||||
| --- | --- | --- |
|
||||
| See available leader groups | `<Space>` | `which-key` opens immediately. |
|
||||
| Find files | `<leader>sf` | Telescope file picker. |
|
||||
| Search text in project | `<leader>sg` | Uses ripgrep through Telescope. |
|
||||
| Search current buffer | `<leader>/` | Compact in-buffer fuzzy search. |
|
||||
| Switch buffers | `<leader><leader>` | Telescope buffer picker. |
|
||||
| Previous / next buffer | `<S-h>` / `<S-l>` | Bufferline navigation. |
|
||||
| Reveal file tree | `\` | Neo-tree reveal. |
|
||||
| Open Oil explorer | `<leader>eo` | Editable directory buffer. |
|
||||
| Format buffer | `<leader>f` | Conform, with LSP fallback. |
|
||||
| Exit terminal mode | `<Esc><Esc>` | Easier than `<C-\><C-n>`. |
|
||||
|
||||
## Motions Worth Practicing
|
||||
|
||||
### Cursor and file movement
|
||||
|
||||
| Motion | Meaning | Practice |
|
||||
| --- | --- | --- |
|
||||
| `h j k l` | left, down, up, right | Use these before arrow keys. |
|
||||
| `w` / `b` | next / previous word start | Move through identifiers quickly. |
|
||||
| `e` / `ge` | next / previous word end | Useful before `c` and `d`. |
|
||||
| `0` / `^` / `$` | line start, first nonblank, line end | Combine with `d`, `y`, `c`. |
|
||||
| `gg` / `G` | file top / bottom | Prefix `G` with a line number. |
|
||||
| `%` | matching pair | Parentheses, braces, brackets. |
|
||||
| `{` / `}` | paragraph or block-ish movement | Good in Markdown and code blocks. |
|
||||
| `<C-d>` / `<C-u>` | half-page down / up | Your `scrolloff=10` keeps context visible. |
|
||||
| `<C-o>` / `<C-i>` | jump back / forward | `jumpoptions=clean,view` restores view better. |
|
||||
|
||||
### Search movement
|
||||
|
||||
| Motion | Meaning |
|
||||
| --- | --- |
|
||||
| `/text` | search forward |
|
||||
| `?text` | search backward |
|
||||
| `n` / `N` | next / previous match |
|
||||
| `*` / `#` | search word under cursor forward / backward |
|
||||
| `<Esc>` | clear search highlight |
|
||||
|
||||
Search is smart-case: lowercase searches are case-insensitive, mixed-case
|
||||
searches become case-sensitive.
|
||||
|
||||
### One-character targeting
|
||||
|
||||
| Motion | Meaning | Example |
|
||||
| --- | --- | --- |
|
||||
| `f<char>` | move to next char | `f)` |
|
||||
| `F<char>` | move to previous char | `F(` |
|
||||
| `t<char>` | move before next char | `dt,` deletes until comma. |
|
||||
| `T<char>` | move after previous char | `cT.` changes back to after dot. |
|
||||
| `;` / `,` | repeat char search forward / backward | Works after `f`, `F`, `t`, `T`. |
|
||||
|
||||
## Editing Grammar
|
||||
|
||||
Vim editing is usually:
|
||||
|
||||
```text
|
||||
operator + motion
|
||||
```
|
||||
|
||||
| Operator | Meaning | Example |
|
||||
| --- | --- | --- |
|
||||
| `d` | delete | `dw`, `d$`, `di"` |
|
||||
| `c` | change | `ciw`, `cib`, `ct,` |
|
||||
| `y` | yank | `yiw`, `yap`, `y$` |
|
||||
| `>` / `<` | indent / unindent | `>ip`, `<ap` |
|
||||
| `=` | auto-indent | `=ip`, `gg=G` |
|
||||
| `gq` | format text with `formatexpr` | Works with LSP when supported. |
|
||||
|
||||
Repeat with `.` after a good edit. This is the fastest way to turn one precise
|
||||
edit into a batch of edits.
|
||||
|
||||
## Text Objects
|
||||
|
||||
Built-in text objects:
|
||||
|
||||
| Text object | Meaning | Example |
|
||||
| --- | --- | --- |
|
||||
| `iw` / `aw` | inner / around word | `ciw`, `daw` |
|
||||
| `i"` / `a"` | inside / around quotes | `ci"`, `ya"` |
|
||||
| `i'` / `a'` | inside / around single quotes | `ci'` |
|
||||
| `i)` / `a)` | inside / around parentheses | `di)` |
|
||||
| `i]` / `a]` | inside / around brackets | `ci]` |
|
||||
| `i}` / `a}` | inside / around braces | `di}` |
|
||||
| `ip` / `ap` | inner / around paragraph | `yap` |
|
||||
|
||||
Configured structural text objects:
|
||||
|
||||
| Text object | Meaning | Example |
|
||||
| --- | --- | --- |
|
||||
| `if` / `af` | inner / around function | `vaf`, `yif`, `daf` |
|
||||
| `ic` / `ac` | inner / around class | `vac`, `yic`, `dac` |
|
||||
|
||||
`mini.ai` adds better around/inside behavior, and Treesitter textobjects add
|
||||
function/class awareness.
|
||||
|
||||
## Search and Replace
|
||||
|
||||
| Goal | Keys |
|
||||
| --- | --- |
|
||||
| Help tags | `<leader>sh` |
|
||||
| Keymaps | `<leader>sk` |
|
||||
| Files | `<leader>sf` |
|
||||
| Builtin pickers | `<leader>ss` |
|
||||
| Word under cursor | `<leader>sw` |
|
||||
| Live grep | `<leader>sg` |
|
||||
| Diagnostics | `<leader>sd` |
|
||||
| Resume last picker | `<leader>sr` |
|
||||
| Recent files | `<leader>s.` |
|
||||
| Commands | `<leader>sc` |
|
||||
| Open-file grep | `<leader>s/` |
|
||||
| Neovim config files | `<leader>sn` |
|
||||
| Project search and replace | `<leader>sR` |
|
||||
|
||||
Hands-on flow:
|
||||
|
||||
1. Use `<leader>sg` to find a symbol or string.
|
||||
2. Use `<C-q>` in Telescope when you want a quickfix list.
|
||||
3. Use `<leader>sR` for real project edits with preview.
|
||||
4. Use `<leader>f` after edits to format.
|
||||
|
||||
## LSP and Code Intelligence
|
||||
|
||||
| Goal | Keys |
|
||||
| --- | --- |
|
||||
| Rename symbol | `grn` |
|
||||
| Code action | `gra` |
|
||||
| References | `grr` or `<leader>gr` |
|
||||
| Implementation | `gri` or `<leader>gi` |
|
||||
| Definition | `grd` or `<leader>gd` |
|
||||
| Declaration | `grD` or `<leader>gD` |
|
||||
| Document symbols | `gO` |
|
||||
| Workspace symbols | `gW` |
|
||||
| Type definition | `grt` or `<leader>gt` |
|
||||
| Toggle inlay hints | `<leader>th` |
|
||||
|
||||
This config also enables LSP CodeLens when the server supports it and linked
|
||||
editing for servers that expose `textDocument/linkedEditingRange`.
|
||||
|
||||
## Diagnostics
|
||||
|
||||
| Goal | Keys |
|
||||
| --- | --- |
|
||||
| Previous diagnostic | `[d` |
|
||||
| Next diagnostic | `]d` |
|
||||
| Diagnostic details | `<leader>de` |
|
||||
| Diagnostics location list | `<leader>q` |
|
||||
| Yank diagnostic context | `<leader>dy` |
|
||||
| Trouble all diagnostics | `<leader>xx` |
|
||||
| Trouble workspace diagnostics | `<leader>xw` |
|
||||
| Trouble current document | `<leader>xd` |
|
||||
| Trouble quickfix | `<leader>xq` |
|
||||
| Trouble loclist | `<leader>xl` |
|
||||
|
||||
Diagnostic display is intentionally quieter:
|
||||
|
||||
- Virtual text shows warnings and errors.
|
||||
- Underlines are limited to errors.
|
||||
- Diagnostic floats use rounded borders.
|
||||
- Jumping diagnostics opens a focused-on-cursor float through `jump.on_jump`.
|
||||

|
||||
| Accept suggestion | `<Tab>` |
|
||||
| Clear suggestion | `<C-]>` |
|
||||
| Accept word | `<C-j>` |
|
||||
|
||||
## Config-Specific Habits
|
||||
|
||||
- Use `<leader>` groups by memory shape: `s` for search, `g` for goto, `G` for
|
||||
git UI, `h` for git hunks, `x` for Trouble, `n` for tests, `w` for windows
|
||||
and sessions, `y` for reference yanks.
|
||||
- Keep relative line numbers on. For example, `d5j` deletes five lines down,
|
||||
and `y3k` yanks three lines up.
|
||||
- Use `.` after focused edits. Example: `ciwnew_name<Esc>` then jump and press
|
||||
`.` to repeat.
|
||||
- Prefer text objects over visual selection when possible: `ci"`, `di)`,
|
||||
`yaf`, `dac`.
|
||||
- Use `<C-o>` after LSP jumps. Your jump list preserves view, so returning to
|
||||
the previous context is less disorienting.
|
||||
- Use `<leader>dy`, `<leader>yr`, and `<leader>yf` when copying context for AI
|
||||
agents or code reviews.
|
||||
- Do not rely on modelines for project settings. This config disables modelines
|
||||
for safer project-local behavior.
|
||||
|
||||
## Five-Minute Drill
|
||||
|
||||
1. Open a project with `nvim .`.
|
||||
2. Press `<leader>sf`, open a file.
|
||||
3. Use `/`, `n`, `N`, `w`, `b`, `%`, `<C-d>`, and `<C-u>` to move without the mouse.
|
||||
4. Change a word with `ciw`, repeat the edit elsewhere with `.`.
|
||||
5. Select a function with `vaf`, then try `yaf` and `daf` in a scratch file.
|
||||
6. Jump to definition with `<leader>gd`, return with `<C-o>`.
|
||||
7. Open diagnostics with `<leader>xx`, then jump with `[d` and `]d`.
|
||||
8. Preview a git hunk with `<leader>hp`, then stage it with `<leader>hs`.
|
||||
9. Run the nearest test with `<leader>nr`.
|
||||
10. Copy an AI-friendly reference with `<leader>yr`.
