Disabled shortcuts

[Anonymous]

Hi,
I am new in archicad, currently creating my first educational project and i faced a problem. After working some time on my project my shortcuts got disabled.. for example the CTRL+U (Multiply) command, however if i double click on a object point and the context menu pops up i can choose it from there. The CTRL+A, CTRL+C, CTRL+V commands still work... Creating new document fixes the issue so i believe it is something i toggled in my current project. Can you help me?

Do the problem occur after a restart of the system? Please, specify operating system and ArchiCAD version?

Yes the problem didn't disappear after restart of the system. The version is ArchiCAD 19 EDU and it is tested on Windows 10 and windows 7 the problem appears on both machines, this is why i thought it is some option that disables them. On both PCs if new project is started the hotkeys work properly
