@leocg My godness, thanks a lot.
I could solve it this way:
Frist, I opened the keyboardshortcuts:
7f460d15-c153-48d0-8296-cbaa910aa278-image.png
Then, I went to the Ctrl+Tab keyboard shortcut:
e44b06f5-27a2-420c-9f96-0a9818d3ee61-image.png
I eliminated those shortcut, and then I went to the shortcuts you told me:
00ad5630-d316-4f98-8701-4100431fa5a5-image.png
I eliminated those too, and replace them with the keyboard shortcut I wanted:
1deb2e95-4d59-4422-b551-b30cb7731e0d-image.png
And, voilá.
Didn't know it had a solution.
Thanks.
