Some Modifier keys do not work on some systems

[Robert Leach]

USE CASE: WHAT DO YOU WANT TO DO?

Use all configured modifier key features.

STEPS TO REPRODUCE AN ISSUE (OR TRIGGER A NEW FEATURE)

1. Run Treeview on Ubuntu
2. Make a selection
3. Hold down "alt" (analog of "command" on mac) & click the zoom-selection button

CURRENT BEHAVIOR

No zoom occurs as a result of step 3.

EXPECTED BEHAVIOR

Zoom to selection (with or without animation depending on default setting) should occur.

DEVELOPERS ONLY SECTION

SUGGESTED CHANGE (Pseudocode optional)

Either request use of the keys from the system or set alternative modifier keys for systems where they are reserved or otherwise do not function.

FILES AFFECTED (where the changes will be implemented) - developers only

unknown

LEVEL OF EFFORT - developers only

minor

COMMENTS

The analog of the "option" key on the mac is called "super" on Ubuntu and is not controlled by the system by default, but it can be, and Lance has it set to perform specific functions that disable it from being able to perform its tasks in TreeView, such as option-scroll to zoom on the cursor.
