Thanks for the feedback!, I am in the process of creating some more tutorials involving improvements I have implemented to enhance ArtRage functionality and to speed up my workflow, for example :

1. Single key press to cycle through each blend modes of a layer

I experiment with blend modes quite a lot and find it a little tedious to select each one in turn, especially on a surface pro with a display setting of 100% (gui elements are very small and fiddly). So I have a single key that auto selects firstly the Normal blend mode from the Tools Layer Options menu and then each subsequent selection of the same key selects each blend mode in turn.

2. Single key press (not holding down H) to flip the canvas.

I don't really like to hold down the H key to keep the flip so a single key press performs the flip and then the same key press unflips.

3. Single key presses to increment and decrement layer opacity to users increment setting

Again at 100% surface pro display the opacity circle is very difficult to select and dial up and down. So I have a key that gets the current opacity value and then one key to increment and one key to decrement at 5%, which can be changed to any value.

I am using a free scripting tool called Autohotkey for all these improvements which I use to map ArtRage keystrokes to a bluetooth numeric keypad
