Four precise line-wise selection commands that pin one end so "inwards" always trims from that side:
Line Select: Select One Line Up – expand selection upward by one whole line (bottom stays pinned)
Line Select: Deselect One Line From Top – shrink selection from the top by one line (bottom stays pinned)
Line Select: Select One Line Down – expand selection downward by one whole line (top stays pinned)
Line Select: Deselect One Line From Bottom – shrink selection from the bottom by one line (top stays pinned)
Works with multiple cursors/selections.
Commands
lineSelect.outwardsUp
lineSelect.inwardsUp
lineSelect.outwardsDown
lineSelect.inwardsDown
Default keybindings (change as you like):
Expand SelectionOne Line Up: ctrl+shift+up
Shrink Selection One Line From Top: ctrl+alt+shift+up
Expand SelectionOne Line Down: ctrl+shift+down
Shrink Selection One Line From Bottom: ctrl+alt+shift+down
Install from source
npm install
npm run build
# in VS Code: F5 to launch Extension Development Host
Package and install
npm run package
code --install-extension line-select-quad-1.0.1.vsix
Why not just keybindings?
Keybindings using cursorMove can expand/shrink, but when you cross the anchor they flip direction. These commands pin the intended end, so “inwards” always trims from that side and never reverses.
