Add Support for “Add Cursors to Line Ends” from VSCode Keymap (i.e. editor::AddSelection)

[stepankuzmin]

Zed currently lacks a built-in hotkey action to add cursors at the end of each line in a selection, a feature that was available in Atom keymaps and is supported in VSCode via Cmd+Shift+L.

Zed provides editor::AddSelectionAbove and editor::AddSelectionBelow, but these commands always extend the selection by adding an extra line above or below, rather than strictly adding cursors to the end of the currently selected lines. As a result, they don’t work as a direct replacement for this functionality.

Expected Behavior:

1. The user makes a selection across multiple lines.
2. The assigned hotkey (e.g., Cmd+Shift+L or a configurable keybinding) is triggered.
3. Zed places a cursor at the end of each line within the selection, enabling simultaneous editing.

Zed has it as editor::SplitSelectionIntoLines

but it is unmapped by default currently in VSCode scheme: cmd-shift-l is already occupied by

zed/assets/keymaps/default-macos.json

Line 392 in adb0d32

"cmd-shift-l": "editor::SelectAllMatches", // Select all occurrences of current selection

Perfect, editor::SplitSelectionIntoLines is exactly what is needed 🙏

and is supported in VSCode via Cmd+Shift+L.

Can you elaborate on that?
For me, this does not seem to work in regular VSCode?

I know that Sublime Text 2 has this keybinding and Zed has a Sublime keymap base with the exact same binding.

Yeah, my bad. This comes from the Atom keymap when enabled.
