What do you mean you can't delete text? Are you able to select the text you want to delete? The delete key doesn't work?
Version of InDesign and OS?
my delete button it's ok.
Only doesn't work the shortcut "Clear" on the menu "Edit"
If you think those current shortcuts are causing problems...highlight the one in question and 'remove' it. You cannot modify the default set though, so if you haven't already, you'll need to make a new keyboard shortcut set.
I try others shortcuts and nothing
I have a personalize shortcut, i'm not working in the default set.
Okay I'm guessing that your using a mac... the clear key on the numpad I believe is reserved for toggling the number pad on and off... so even though you set the clear key as a hotkey in InDesign, that functionality is being preceded by the OS functionality of toggling. Your original post sort of sounded like you couldn't use the delete key to delete text in InDesign...
Yes I've a mac.
This trouble only happens on InDesign.
For exemple, if i select two or more letters i can delet it, but if i put the cursor in the middle of tu letter i can't delet it.
