Gemini PDA Keyboard - Alt-keys not Working

How to properly choose keyboard layout in Sailfish for Gemini PDA? Anyone have an idea?

I don’t know what “locale” language you use on Gemini. I use Slovak. There is no HW keyboard on Gemini for Slovak, so I solved it like this.

Maybe it will help you.
Some keyboard shortcuts (mostly) work, e.g. Ctrl+C, Ctrl+V. It is possible to switch the layout of the Ctrl+space bar keys in the terminal, but it does not work properly for me.
