Regular shortcuts consist of a single key press combination. For example, the Edit->Delete command has the shortcut of Ctrl+D. This means you have to press the Ctrl key and, while holding it down, press the D key.

Another example is Ctrl+Alt+O for the Tools->Options command, where you need to press and hold the Ctrl and Alt keys and then press the O key.

Chord shortcuts consist of two consecutive set of key press combinations. For example, the Go->Outline command has the shortcut (Ctrl+G, L).

This means you have to press the Ctrl key and, while holding it down, press the G key. This is the first part of the chord. You will see in the status bar the following:

This means that Achieve Planner is waiting for you to enter the second part of the chord. In this case, you need to press the L key (without holding down the Ctrl or any other key) to complete the shortcut.

Some chord shortcuts require you to press a modified key (Ctrl, Alt, or Shift) on each of the two key press combinations. For example, the Edit->Drop Copy as Child command:

This shortcut requires Ctrl+Alt+Shift+V on the first part of the chord, and Shift+C on the second part.
