Something changing how many keys are read in Jedit

Question

Occasionally something will happen in Jedit (I guess I am pressing some key sequence that is putting me into some other mode), and the keys I press show up as all sort of strange symbols. I don't know how to fix the behavior; closing and re-opening Jedit doesn't help. The only thing that works is restarting my computer.

I also notice that sometimes there is a difference between right ctrl and left ctrl. For example, right now left ctrl + s will save my file, but right ctrl + s inserts the symbol ß into the buffer.

Can someone please explain why this happens?

I guess this is probably more a OS thing than a jEdit (not Jedit) thing. You can see the key events that are sent to jEdit with the help of Utilities -> Troubleshooting -> Keyboard Tester... and you will probably see the your OS is sending wrong things to jEdit. Maybe you are using Windows and pressed the default Alt+TAB shortcut to change the keyboard layout. You can also show the language bar in your Taskbar to always see which keyboard layout is selected currently. Oh, btw. if you close jEdit with the red cross in the upper right, you are probably only closing the View, not quitting jEdit. If you press Ctrl+Q or select File -> Exit, then jEdit is really closed and can be restarted. If you still think this is a jEdit rather than an OS problem, you might consider opening a bug ticket for jEdit.
