Questions:

• Is there a way to test focus by script (If left file display is active, do this… If tree is activate, do this…) ?
• Is there a way to test view mode by script (details, thumbnails…) ?

You can use command.IsSet in scripts to test the same things @if does in basic buttons.

Simple example here: Multiple file and inline rename - #12 by Leo
