I know I can switch to a glossary entry (e. g. from an action in an activity diagram) by using ctrl-leftclick.
Is there also a quick way (i. e. keyboard shortcut and/or mouse action) to return to the place I came from (e. g. in the said activity diagram/action), similar to a browser’s “back” button? That would be very helpful.
After contacting VP support, I got the information that I can use alt-(left key), which is the default keyboard shortcut for “previous diagram”. This works.
Since I wanted to use this feature in a presentation without continously switching a hand between keyboard and mouse (ctrl-(left click) to go the glossary term vs. alt-(left key) to go back to diagram), I redefined the keyboard shortcut to alt-z which works well for the US keyboard layout. (Mnemonic: ctrl-z goes back to the previous edit state, alt-z goes back to the previous diagram.)
