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

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.
