I have one very annoying issue with Eclipse under Windows. The key bindings for Ctrl+Alt+key are activated when I press Right Alt+ key. This made me viewing the list of key bindings and remove all bindings for Ctrl+Alt+key, which I would find usable, when they wouldn't block inputing characters.
I'm using keyboard mappings, where right conrol is a switch key for national characters. Right Alt+e = ę, Right Alt+O = ó etc. Eclipse seems not to be compatibile with such keyboard layouts.
Is there any possibility of switching off this behaviour and making Eclipse to use key bindings only with Left Alt key?
No, eclipse doesn't differentiate between which CTRL key is used to execute a keybinding. It's listening for any key pressed with a modifier (CTRL, ALT, etc) in an SWT filter.
If it's not the OS consuming the CTRL and generating the national character then the eclipse keybindings could consume it before your get your correct character.
