A41/Straight line with UltraNav in Photoshop Bonus!

[cruzlite]

Ever try to draw a straight line in PS with a mouse/trackball?...
For years now I have wanted to...
In PS (I'm using Elements II)...
With UltraNav/constrained motion enabled, (I use L-control key)...

[I find I have to depress & hold left click], then depress & hold enabled key, (in my case; L control key)...motion on the touchpad is then transferred to whatever tool is enabled in PS! (Vertcally & horizontally)

Note; Step in brackets [] above is not in UltraNav directions:
---Cntrlpannel/mouse/UltraNav/TouchPad settings/pointer motion/constrained motion---
This step is required to make process work on my machine.
