Tippies can be quickly adopted with immediate workflow benefits...
Pointing devices (mouse, trackpad, pen, etc.) are used to move around in Hyperspace. These have a main (left) button or equivalent (e.g., one-finger tap on trackpad, tap-n-hold on iPad). This works to select or activate whatever the pointer is pointing to.
Pointing devices also have a secondary (right) button or equivalent (e.g., double-finger tap on trackpad).
This works differently in different places, but right-clicks almost always save time:
Lists and command icons - context-sensitive popup menu listing things one can do (e.g., make favourite, edit) for the item that the cursor points to.
Order-entry - right-click anywhere in an order detail box to accept the order (instead of clicking on the Accept button).
NoteWriter - when working with tri-state buttons (+ button for positive and - button for negative), a right-click is the equivalent of clicking the - button.
SmartLists - when working with SmartText and selecting items in a SmartList, a right-click is the equivalent of the Enter key for moving to the next editable item in the SmartText.
There's more! Experiment with right-click (or equivalent) to learn new efficiencies without taking one's hand off the pointing device.
