Multiple cursors in Skink: Ctrl+D, Alt+click and more

Ctrl+D for the next match, Alt+Shift+↓ for the line below.

Press Ctrl+D to select the word under the cursor, then press it again to add a cursor at the next match. Type, and every cursor types. Esc goes back to a single cursor.

This works like Sublime Text and VS Code, with Micro’s action names.

Multiple cursor keys

Key	Typed command	Does
`Ctrl`+`D` or `Alt`+`N`	`:addcursor`	Select the word; again: add a cursor at the next match
`Alt`+`X`	`:skipcursor`	Skip this match and select the next one
`Alt`+`Shift`+`↑` / `↓`	`:cursorabove` / `:cursorbelow`	Add a cursor on the line above / below
`Ctrl`+`Alt`+`↑` / `↓`	same	An alternative binding for the same
`Alt`+click		Add a cursor, or remove the one under the mouse
`Esc` or `Alt`+`C`	`:onecursor`	Back to one cursor

The status line shows ×N while you have N cursors.

What happens at every cursor

Typing, deleting, moving, indenting and moving lines (Alt+↑ / ↓).
Case changes, join, sort and trim (:UpperCase, :LowerCase, :TitleCase, :JoinLines, :SortLines, :TrimTrailingWhitespace).
One undo (Ctrl+Z) undoes the change at all cursors.

Copy and paste with several cursors

Copy with N cursors puts one line per cursor on the clipboard.
Pasting N lines into N cursors gives each cursor its own line.

So you can copy five values from five places and paste them into five other places in one go.

Examples

Rename a variable within a function

Put the cursor on the name and press Ctrl+D once to select it. Press it again for each use you want, and Alt+X to skip a match you do not want. Type the new name.

For a rename across files that understands your code, use the language server instead: Alt+Shift+R. See Refactoring.

Add a comma at the end of ten lines

Put the cursor on the first line and press Alt+Shift+↓ nine times. Press End, then type ,.

Edit every match in the file at once

For a plain replace-all, the find bar is quicker: Ctrl+F, type, Tab, type the replacement, Enter. See Find and replace.

Bind the multiple cursor actions

The actions use Micro’s names, so they can be bound in bindings.json:

Action	Does
`SpawnMultiCursor`	Select the word, then add a cursor at the next match
`SpawnMultiCursorUp` / `SpawnMultiCursorDown`	Add a cursor above / below
`SkipMultiCursor`	Skip this match and select the next
`RemoveMultiCursor`	Remove the newest cursor
`RemoveAllMultiCursors`	Back to a single cursor

For example, to remove the newest cursor with Alt+Shift+X (Micro’s format writes Shift as a capital letter):

{ "Alt-X": "RemoveMultiCursor" }

See Key bindings.
