-- Exit terminal mode in the builtin terminal with a shortcut that is a bit easier
-- for people to discover. Otherwise, you normally need to press <C-\><C-n>, which
-- is not what someone will guess without a bit more experience.
--
-- NOTE: This won't work in all terminal emulators/tmux/etc. Try your own mapping
-- or just use <C-\><C-n> to exit terminal mode
vim.keymap.set('t', '<Esc><Esc>', '<C-\\><C-n>', { desc = 'Exit terminal mode' })

-- TIP: Disable arrow keys in normal mode
-- vim.keymap.set('n', '<left>', '<cmd>echo "Use h to move!!"<CR>')

-- vim.keymap.set('n', '<up>', '<cmd>echo "Use k to move!!"<CR>')
-- vim.keymap.set('n', '<down>', '<cmd>echo "Use j to move!!"<CR>')

-- Keybinds to make split navigation easier.
-- Use CTRL+<hjkl> to switch between windows
-- See `:help wincmd` for a list of all window commands

-- Quit keymaps - easier ways to close Neovim (using capital Q to avoid conflict with diagnostic quickfix)
-- Session management is automatic via auto-session plugin (saves on exit, restores on startup)
