Dear readers of this list,

I am using Inkscape 1.0.2 (1.0.2+r75+1) with Ubuntu 20.04 with all updates. I have a Wacom Graphire4 tablet, the stylus works out of the box. However, buttons and scroll wheel on the pad have to be configured seperatly to work properly, for example with xsetwacom, which I did. But configuration with xsetwacom has the disadvantage of working globally for all applications, and it has to be repeated every time you start the machine. My xetwacom script:

#!/bin/bash
#Used to setup my Wacom Tablet (Graphire4)
echo "Setting up Wacom Tablet..."
echo "Configuring pen buttons..."
sleep 0.1
xsetwacom --set "Wacom Graphire4 6x8 Pen stylus" button 2 "key +ctrl z -ctrl"
echo "Configuring tablet buttons..."
sleep 0.1
xsetwacom --set "Wacom Graphire4 6x8 Pad pad" button 8 "key +ctrl 4 -ctrl"
sleep 0.1
xsetwacom --set "Wacom Graphire4 6x8 Pad pad" button 9 "key +1 -1"
echo "Configuring tablet scroll wheel"
sleep 0.1
xsetwacom --set "Wacom Graphire4 6x8 Pad pad" RelWheelUp "key +"
sleep 0.1
xsetwacom --set "Wacom Graphire4 6x8 Pad pad" RelWheelDown "key -"
echo "Done!"
exit 0

Unfortunately, the dialog in Inkscape which allows configuration of the buttons escapes my abilities to use it. I detected no way to modify any of the keys, not to mention the scroll wheel. In Gimp, which includes a similar dialog, you have to click twice on the key you want to modify, and then type the key or key combination to be assigned to the corresponding button. How is it done in Inkscape?

Thanks for any helpful hints in advance!
