Hi Brig,
Welcome to the site and to farr
You could actually set up FARR to do what you want:
- You would do it by setting a custom hotkey in FARR, and specify a search string to trigger when you hit that hotkey
- And then use an alias pack like this one which includes commands to manipulate the last active window. I think the exact text you'd use with that would be "Window Management Minimize\n".
However, let me say that this sounds messy because it is messy to do in FARR, because FARR is not meant to be used to provide hotkey triggering of generic actions like window controls. There are a lot of hotkey programs that can so this kind of stuff really well, and a lot of people on DC use the AHK language to write scripts to handle hotkeys and manipulate windows.. And it seemed like not a great idea to try to make FARR a generic program for handling hotkeys and macros.
In short, you can do it in FARR but you probably shouldn't. If you like configuring hotkeys to do things, do yourself a favor get yourself a nice hotkey program, there are a lot of good free ones (here's just
one example).
ps. Where FARR can excel and do things better than hotkey programs is if you like to press a hotkey and have FARR pop up with a MENU of options.. In this case you can easily set custom hotkeys in FARR that tell FARR to display and start out with a search string you specify, which can match an alias that shows choices you can select from, etc.
