I did have a look at their tutorial and found it very technical, difficult to read and was unable to find any information on whether it is possible to send characters/text that are not part of the current keyboard layout. From what you describe I can guess now that kmonad is not really suited to what I am trying to achieve though.

That sounds a lot better than what I imagined. I’ll have to try that out then. Thanks

The way I understood the compose key is that it requires me to type a combination in order to get the actual character I want.

What I want is to use the right alt key more like a layer modifier (just like shift works to switch between numbers and signs for example), in order to get my special characters

I haven’t used PDFDing before but honestly that description sounds a bit unituitive to me. I would expect to select the color first and then markt the text but maybe this is just because I haven’t seen the interface
