Dear Choroba,

Thank you very much for the script. Unfortunately, it did not work on windows (I will try it on Linux tomorrow, although the target application must run on windows). The situation is: if I press AltGr, your script prints Control + ALT_R, but if I hold it down and press the minus key (which would create the asterisk), only minus appears in the entry. The situation is similar if I want to use 3 keys to create the asterisk: control + left alt + minus key. In this case also only the minus will remain in the entry at the end of the process.

I also tried Term::Readkey to get the asterisk (not entered from numpad), but this is very difficult to implement in a Tk environment.
