New hotkeys for Header Editor

It would be nice to have some hotkeys to change the values of some attributes in the header editor. For example:

Ctrl+d: set "Default track" flag vale to on/off Ctrl+e: set "Track enabled" flag vale to on/off Ctrl+f: set "Forced display" flag vale to on/off Ctrl+h: set "Hearing impaired" flag vale to on/off

Thanks!
