I've been meaning to ask this for quite a while:
I'm having difficulty shaking the habit of using Command-W, and I end up closing tabs in the Titler, and not the Titler itself, and then having to reopen the tab I was using last, before going old school with the mouse.
Is there a keyboard alternative to clicking the red Close Window button?
No there is not.
I made a feature request for the option to minimize the Title.
And be able to maximize from the windows taskbar.
Alt-F4 works for me. Same as with any other Windows program.
I looked up the Mac equivalent and it seems to be Command-W. So that closes the most current panel? Sounds to me like you should submit a bug report.
