I've tried most of what I could find and found them never satisfying, especially the layout. (With due respect to the creators nonetheless!)
Then, I started thinking that I'd probably spend much less time just manually generating an image for it myself and use it as splash image. And since I'm quite adept in css, I decided to do it in html/css, so that I can easily change it if my hotkeys change. Call it semi-manually.
I gather now that if I would have started out like that, the time needed to create and update this in my whole life, would be less than looking for or trying to make an all-round automatic one myself.
Anyway, it's here now and I'd like to share it with you.
If you like to have one yourself, just go over to this page on my attic, download the package and edit the self-explanatory HTML to match your buttons, possibly add your own custom icons.
(You may share your own icons with me if you like; I'll update the package ... if they are nice ;-p )
Then take a screenshot and use the script below to use it as a Buttons Help Overlay.
My splashimage script:
SplashImage, C:\Users\Ruben\Documents\Configs`, addresses\Software\AH\Buttons Help\SShot.gif, B
WinSet, TransColor, 000000 20,SShot.ahk ; not working ??
I hope you peeps like it so I can return something for all the help I got here.
