Usage

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

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.
