screenshot showing the two conflicted mnemonics

When kate is showing tabs for open files, if you press the ALT key, you will notice that each tab is assigned a mnemonic according to its file name (I suppose). This causes issues if the same mnemonic is used in some other component.

STEPS TO REPRODUCE
1. create two or more documents and save these.  For one of these, use a filename that starts with "a" (like "a file.txt"). The other two filenames don't really matter.
2. go to a document the its filename isn't the one starting with "a"
3. Try to globally replace something. This usually would involve hitting CTRL+R, then typing what you want to replace to what and then hitting ALT+A (the mnemonic for "Replace &All").

OBSERVED RESULT
Unfortunately, instead of performing the global replacement, it switches tabs :(

EXPECTED RESULT
It should perform the f**ing replacement :)
