-- PERSONAL KEYMAPS (ORIGINAL WORKFLOW)
-- =============================================================================

--- Select the entire file contents (visual mode).
keymap.set("n", "<leader>u", function()
  vim.cmd("normal! ggVG$")
end, { desc = "Select the whole file" })

--- Duplicate the current line below.
keymap.set("n", "<leader>4", function()
  -- Copy current line and paste below
  vim.cmd("normal! yy")
  vim.cmd("normal! p")
end, { desc = "Copy the entire line and paste just below" })

--- File management — save, quit, force quit, source, and clear search.
keymap.set("n", "<leader>w", ":w<CR>", { desc = "Save the current file" })
keymap.set("n", "<leader>xa", ":xa<CR>", { desc = "Save and close all the files" })

--- Increment/decrement the number under the cursor.
keymap.set("n", "<leader>+", "<C-a>", { desc = "Increment number" })

keymap.set("n", "<C-e>", "10<C-e>", { noremap = true, silent = true })
keymap.set("n", "<C-y>", "10<C-y>", { noremap = true, silent = true })

--- Close the current buffer with a confirmation prompt if modified.

--- TODO: Fix this keymap
