Ctrl+F1 stop working

[Arnau Bria]

Hi all,

I don't know when neither why my Ctrl+F1 o F2, etc.. have sttoped
working. I used it for changing from one workspace to an other.

I went to shortcuts and tried to add it again, but when I try so, it
asks for a command and not an action (swithching workspcae, i.e).

Anyone could tell me how to re-enable such behaivour?

TIA
