I use Preview to view PDF files (duh) and sometimes annotate them as well as search them profusely. I keep using the Command-Backspace combination to try to delete the current line I'm writing in the annotation or to clear the search box, but to my dismay it sends the currently open PDF file to the trash!
I'm used to Command-Backspace deleting the whole line in other, more write or text-input oriented, software, such as TextEdit even (which I don't really use, but it is another OSX default, so I'd think some consistency is to be expected?) .
Is there any way to disable this keyboard shortcut in Preview? I don't even need it to do what I expect it to, I just want it to stop deleting my files!
