The current shortcut key to move the filters with a rectangle VUI is clicking inside the rectangle and holding down Shift. However since this creates a problem with the Text: Rich filter since Shift is used to select characters that have been typed then this function is left out of Text: Rich. So how about changing the shortcut key to Alt instead? I don’t believe that Alt is used for anything in any of the filters with rectangle VUI. Doing this would allow this function to also be in Text: Rich without any clashes. Plus it would make it consistent with how Alt is seemingly used elsewhere in Shotcut as the key for movement like to seek faster in both the regular and keyframe timelines.
If this is agreed on then I it’d be nice to take this further and add the function of locking the movement of the rectangle VUI to up/down or left/right for those that want to be more precise with placement. This would be done by having it that if you hold Alt while also holding Shift then it would restrict movement to up and down and if you hold Alt while also holding Ctrl then it would restrict movement to left and right.
I wasn’t aware that GIMP had a similar function. I always just used the arrow keys if I wanted to lock it to one direction and do it while holding Shift if I wanted to move faster.
I just tested using Ctrl in GIMP and I see it’s not a strict lock. It can be annoying though because if you move the mouse past the guide made by holding Ctrl the object you are moving will do a big jump outside the guide. Still thanks for letting me know.
