Is it possible to get rid of the delay between right-clicking and seeing the context menu?
Tapping with the trackpad has a delay while the trackpad decides which gesture you are performing. Disabling some gestures will remove this delay in certain cases:


If “Smart zoom” is turned on, then a two-finger tap needs to wait to see if you are performing a two-finger double tap.
If dragging is enabled (“with drag lock” or “without drag lock”), then a one-finger tap needs to wait to see if you are performing a double tap. (This setting hides in the Accessibility preference pane.)
