title: Multiple keyboard shortcuts for action in Qt Designer
body: <p>I'm having a weird problem with Qt designer. I have the following shortcut for a refresh action: <kbd>F5</kbd> , <kbd>Ctrl</kbd> + <kbd>R</kbd></p>
  
  <p>The idea is that on Macintosh, <kbd>Ctrl</kbd> + <kbd>R</kbd> maps to <kbd>Command</kbd> + <kbd>R</kbd> which is more intuitive and on Windows, <kbd>F5</kbd> does the job.</p>
  
  <p>The problem is that only the first shortcut seems to be active. Is there a way for me to change the action's shortcut so that we have <kbd>Ctrl</kbd> + <kbd>R</kbd> active on Mac and <kbd>F5</kbd> everywhere else? I know I can do this in code but I'd rather do it in designer.</p>
