Keymap

💡 Mappings marked (LSP) require an active language server for the file.

💡 Mappings marked (TS) require a tree-sitter grammar for the filetype.

Minor modes

These sub-modes are accessible from normal mode and typically switch back to normal mode after a command.

View mode

Accessed by typing z in normal mode.

View mode is intended for scrolling and manipulating the view without changing the selection. The "sticky" variant of this mode (accessed by typing Z in normal mode) is persistent; use the Escape key to return to normal mode after usage (useful when you're simply looking over text and not actively editing it).

Key Description Command

k, up Scroll the view upwards scroll_up
Ctrl-f, PageDown Move page down page_down
Ctrl-b, PageUp Move page up page_up
Ctrl-d Move half page down half_page_down
Ctrl-u Move half page up half_page_up

Goto mode

Accessed by typing g in normal mode.

Jumps to various locations.

Key Description Command

y Go to type definition (LSP) goto_type_definition
r Go to references (LSP) goto_reference
i Go to implementation (LSP) goto_implementation
a Go to the last accessed/alternate file goto_last_accessed_file
m Go to the last modified/alternate file goto_last_modified_file
n Go to next buffer goto_next_buffer
p Go to previous buffer goto_previous_buffer
. Go to last modification in current file goto_last_modification

Match mode

Accessed by typing m in normal mode.

See the relevant section in Usage for an explanation about surround and textobject usage.

Key Description Command
m Goto matching bracket (TS) match_brackets
s <char> Surround current selection with <char> surround_add
r <from><to> Replace surround character <from> with <to> surround_replace
d <char> Delete surround character <char> surround_delete

TODO: Mappings for selecting syntax nodes (a superset of [).

Window mode

This layer is similar to Vim keybindings as Kakoune does not support window.

Key Description Command
w, Ctrl-w Switch to next window rotate_view

J Swap window downwards swap_view_down
K Swap window upwards swap_view_up
L Swap window to the right swap_view_right

Space mode

Accessed by typing Space in normal mode.

This layer is a kludge of mappings, mostly pickers.

Key Description Command
f Open file picker file_picker
F Open file picker at current working directory file_picker_in_current_directory
b Open buffer picker buffer_picker
j Open jumplist picker jumplist_picker
k Show documentation for item under cursor in a popup (LSP) hover

Unimpaired

Mappings in the style of vim-unimpaired.

Insert mode

Insert mode bindings are somewhat minimal by default. Helix is designed to be a modal editor, and this is reflected in the user experience and internal mechanics. For example, changes to the text are only saved for undos when escaping from insert mode to normal mode. For this reason, new users are strongly encouraged to learn the modal editing paradigm to get the smoothest experience.

Key Description Command
Escape Switch to normal mode normal_mode
Ctrl-s Commit undo checkpoint commit_undo_checkpoint
Ctrl-x Autocomplete completion
Ctrl-r Insert a register content insert_register
Ctrl-w, Alt-Backspace Delete previous word delete_word_backward
Alt-d, Alt-Delete Delete next word delete_word_forward
Ctrl-u Delete to start of line kill_to_line_start
Ctrl-k Delete to end of line kill_to_line_end
Ctrl-h, Backspace Delete previous char delete_char_backward
Ctrl-d, Delete Delete next char delete_char_forward
Ctrl-j, Enter Insert new line insert_newline

These keys are not recommended, but are included for new users less familiar with modal editors.

Key Description Command
Up Move to previous line move_line_up
Down Move to next line move_line_down
Left Backward a char move_char_left
Right Forward a char move_char_right
PageUp Move one page up page_up
PageDown Move one page down page_down
Home Move to line start goto_line_start
End Move to line end goto_line_end_newline

If you want to disable them in insert mode as you become more comfortable with modal editing, you can use the following in your config.toml:

[keys.insert]
up = "no_op"
down = "no_op"
left = "no_op"
right = "no_op"
pageup = "no_op"
pagedown = "no_op"
home = "no_op"
end = "no_op"

Select / extend mode

This mode echoes Normal mode, but changes any movements to extend selections rather than replace them. Goto motions are also changed to extend, so that vgl for example extends the selection to the end of the line.

Search is also affected. By default, n and N will remove the current selection and select the next instance of the search term. Toggling this mode before pressing n or N makes it possible to keep the current selection. Toggling it on and off during your iterative searching allows you to selectively add search terms to your selections.
