NVIM key mapping

 To determine if a keymap is bound in Neovim, or to see what a specific key or key combination is mapped to, several methods can be employed:

• Using the :map command (and its variants):

  • :map: Lists all mappings in all modes.
  • :nmap: Lists mappings specifically for Normal mode.
  • :vmap: Lists mappings for Visual mode.
  • :imap: Lists mappings for Insert mode.
  • :cmap: Lists mappings for Command-line mode.
  • To check a specific key, append it to the command, e.g., :map <Leader>s to see what <Leader>s is mapped to.
• Using verbose map:

  • To see where a mapping was defined (e.g., in a plugin or your init.vim), use verbose map followed by the key or key sequence. For example, :verbose map <C-s> will show the mapping and the file it originated from.
• Using mapcheck():

  • The mapcheck() function can be used in a script or on the command line to programmatically check if a mapping exists for a given key sequence. For example, :echo mapcheck('<C-s>') will return a non-empty string if a mapping exists for <C-s>.
• Using maparg():

  • To get detailed information about a specific mapping, including its right-hand side (rhs), use maparg(). For instance, :echo maparg('<Leader>f', 'n') will return a dictionary containing information about the <Leader>f mapping in Normal mode.
• Using the WhichKey plugin:

  • Plugins like folke/which-key.nvim provide a visual way to explore keymaps. As you type a key sequence, a popup appears showing the available mappings that start with those keys, making it easy to discover what a key is bound to.

These methods provide comprehensive ways to inspect and understand key bindings within your Neovim environment.
