Yes. Somehow _this_ key combination (code 134) is assigned to
the keypad decimal point (numeric keypad decimal separator,
usually code 93), which is wrong - but matches your observation
that dots will appear in input fields. I have no idea where
this code is introduced. Maybe some crazy auto-detect "magic"
usually found in big desktop environments?

When you have commands that work, you can start "programming
the keys" to act as intended, using xmodmap. It's still strange
why code 133 and 134 are being treated that way.
