AeroSnap lets you quickly snap a window to any of the 4 screen edges, resizing it to half of screen size. This makes it easy to display 2 windows side-by-side.

The following steps will add 4 keyboard shortcuts Ctrl+Alt+Left/Top/Right/Down to JWM's configuration. The code requires wmctrl to be installed. Please note that the windows will be horizontally or vertically maximized. This allows to restore them (approximately!) to their previous size.

Step 1: Open file /root/.jwm/jwmrc-personal with an editor
Step 2: Insert following 4 red lines (If your browser shows more than 4 lines: copy the whole red section to your editor. This will eliminate any confusing line wraps and you should end up with only 4 lines)
Step 3: Save jwmrc-personal
Step 4: Restart JWM (Menu: Shutdown > Restart JWM or from Terminal: jwm -restart)

That's all.

Probably. I tried to keep the code as short as possible, but this may have pushed the wm to its limits. Checking my own implementation I notice that I added a step to clear the maximized status of a window before changing back to normal size. Can't remember why I did it (my original code works for me), but it could well be that I faced the same issues as you did in some distributions.

This is basically what I use now. Maybe you can kindly try it and report back if it solves your issue:

Code: Select all

As for the Windows key: You can use it as a modifier key or a normal key, but both? How should this possibly work? You can however use different assignments for left and right Windows keys.
