About keyboard shortcuts and input focus in a Channel Panel

A keyboard shortcut takes effect for the channel or gang with the input focus. You must make sure that the channel or gang that you want to control has the input focus before you use a keyboard shortcut.

A blue border indicates the channel or gang with the input focus.

You can give a channel or gang the input focus as follows:

To give a gang the input focus, click once anywhere on the gang.
To give a single (un-ganged) channel the input focus, click once anywhere on the channel.

For an individual channel in a gang, an input focus is not indicated by a blue border.

To give an individual channel in a gang the input focus, double-click on the channel. This also displays the overlay transport controls for the channel in focus.
