title: R studio shortcut to switch tabs:ctrl+alt+left/right not working
body: <p>I am facing problems when using keyboard shortcuts to switch in between tabs in Rstudio: even though I have disabled the Hot Keys for the graphical card, <kbd>ctrl</kbd>+<kbd>alt</kbd>+<kbd>left</kbd>/<kbd>right</kbd> to switch between tabs does not work. But, switching to first/last tab using <kbd>ctrl</kbd>+<kbd>alt</kbd>+<kbd>shift</kbd>+<kbd>left</kbd>/<kbd>right</kbd> is working. I am using the latest version of R, Rstudio, and Windows 7. </p>
  
  <p>Has anyone an idea how to overcome this issue? (it seems I am not alone facing this problem : <a href="https://support.rstudio.com/hc/communities/public/questions/201564413-Keyboard-shortcut-not-working-on-Windows-7" rel="nofollow">https://support.rstudio.com/hc/communities/public/questions/201564413-Keyboard-shortcut-not-working-on-Windows-7</a>). Thank you for your answer.</p>
