Congratulations on releasing: 4.12.0
There are no entries in the Window Manager Keyboard settings to configure shortcuts for the new tiling options that were introduced:
*) Tile window top right
*) Tile window top left
*) Tile window bottom right
*) Tile window bottom left
In Openbox I normally default all the tiling options to Super+NumpadKey for placement (with the 5 key serving as maximise). It would be great to be able to do that with Xfwm4.
They are not found in the keyboard manager but in the window settings.
The option to set shortcuts to tile to quarters have also already been introduced shortly: https://bugzilla.xfce.org/show_bug.cgi?id=11636
That is indeed where I was looking (I still only have the 4 old ones). It sounds like I just need to wait for them to show up now.
Sorry about the duplicate ticket; I somehow missed the other one.
