How to control iconify minimize behavior

[LambdaFox]

I am transitioning over from Windows XP to Lubuntu 14.04.

In XP I had a system utility installed that allowed me to minimize any window to the system tray by holding the shift key and clicking the minimize button on a window. When I did this, the application would no longer appear on the task bar.

I looked at the pages for alltray and obapps, but I there isn't enough information there for me to clue in on whether those are where I need to go. Any suggestions, advice?

alltray is your best bet.
it's not a 100% replacement of what you describe, though.
another possibility is to make ALL windows display without text, icons only, in your taskbar. or not at all. look at the options for your panel's "window list" (or similar).
