I've added some hotkeys to the FARR MultiMonitor plugin. Note that they are currently hard-coded, so if you need these key combinations for something else, you'll have to disable them for the FARR MultiMonitor plugin (in the options dialog).
Hotkeys: move FARR window to next/last monitor or center it with hotkeys
Win + Left : move FARR window to monitor on the left
Win + Right : move FARR window to monitor on the right
Win + Home : center FARR window
The centering is especially useful for FARR MultiMonitor users which are using two monitors with different resolutions (that would be me
). When directory browsing (or when using the 'not yet released' OpenWith plugin) it will usually resize to full height at first. Since FARR only knows about one monitor, and all this happening on the one with the smaller screen resolution, FARRs top will go off the screen, then, narrowing the search, it will shrink, with the top still off the screen.... hit Win + Home, and everything is back to normal
The hotkeys can be used by themselves, too. I.e. you could disable automatic centering when FARR appears and/or moving the FARR window to the active monitor, and just use the hotkeys to center the FARR window and move it around.
