## Set (or Extend) Left Selection

When playing or recording, sets the left boundary of a potential selection by moving the cursor to the current position of the green playback cursor (or red recording cursor). The selection can then be drawn by using "Set (or Extend) Right Selection"(below).

When stopped, increases the size of the selection by extending it to the left. The amount of increase is dependent on the zoom level. If there is no selection one is created starting at the cursor position.

## Set (or Extend) Right Selection

This is a quick way to mark a selection for future editing while playing or recording. Selections can be labeled while playing or recording using Edit > Labels > Add Label at Selection or shortcut Ctrl + B.
