For example, when pressing and holding the shift button, an ellipsis (...) should appear next to each session method in the menu. The following modes are currently available:
- shift : Open the options for that session method
- q : Add the method to the task processor [q]ueue
- e : Open (and [e]dit) the m-file for the session method
