< p > One-way key remapping is temporarily supported via a simple TOML configuration
file. (More powerful solutions such as rebinding via commands will be
available in the future).< / p >
< p > To remap keys, write a < code > config.toml< / code > file in your < code > helix< / code > configuration
directory (default < code > ~/.config/helix< / code > in Linux systems) with a structure like
this:< / p >
< pre > < code class = "language-toml" > # At most one section each of 'keys.normal', 'keys.insert' and 'keys.select'
[keys.normal]
C-s = " :w" # Maps the Ctrl-s to the typable command :w which is an alias for :write (save file)
C-o = " :open ~/.config/helix/config.toml" # Maps the Ctrl-o to opening of the helix config file
a = " move_char_left" # Maps the 'a' key to the move_char_left command
w = " move_line_up" # Maps the 'w' key move_line_up
" C-S-esc" = " extend_line" # Maps Ctrl-Shift-Escape to extend_line
g = { a = " code_action" } # Maps `ga` to show possible code actions
" ret" = [" open_below" , " normal_mode" ] # Maps the enter key to open_below then re-enter normal mode
[keys.insert]
" A-x" = " normal_mode" # Maps Alt-X to enter normal mode
j = { k = " normal_mode" } # Maps `jk` to exit insert mode
