Usage

(Currently not fully documented, see the keymappings list for more.)

See tutor.txt for a vimtutor-like introduction.

Registers

Vim-like registers can be used to yank and store text to be pasted later. Usage is similar, with " being used to select a register:

• "ay - Yank the current selection to register a.
• "op - Paste the text in register o after the selection.

If there is a selected register before invoking a change or delete command, the selection will be stored in the register and the action will be carried out:

• "hc - Store the selection in register h and then change it (delete and enter insert mode).
• "md - Store the selection in register m and delete it.

Special Registers

There is no special register for copying to system clipboard, instead special commands and keybindings are provided. See the keymap for the specifics.

Surround

Functionality similar to vim-surround is built into helix. The keymappings have been inspired from vim-sandwich:

• ms - Add surround characters
• mr - Replace surround characters
• md - Delete surround characters

ms acts on a selection, so select the text first and use ms<char>. mr and md work on the closest pairs found and selections are not required; use counts to act in outer pairs.

It can also act on multiple seletions (yay!). For example, to change every occurance of (use) to [use]:

• % to select the whole file
• s to split the selections on a search term
• Input use and hit Enter
• mr([ to replace the parens with square brackets

Multiple characters are currently not supported, but planned.

Textobjects

Currently supported: word, surround.

• ma - Select around the object (va in vim, <alt-a> in kakoune)
• mi - Select inside the object (vi in vim, <alt-i> in kakoune)

Textobjects based on treesitter, like function, class, etc are planned.
