In a recent conference call with #libreoffice-design team it came up that if rulers are going to be hidden by default (something already being worked on), then we need an easy shortcut to toggle ruler's visibility. Ctrl+R is often used to align text to right, so Ctrl+Shift+R it is. Unfortunately Ctrl+Shift+R was used for redraw before, which would go now unbinded as something only developers would need. If you happen to use it regularly, please speak up, maybe something such as Ctrl+Shift+F5 would be just as good.
The patch is here: https://gerrit.libreoffice.org/#/c/13326/ It touches the following components: DrawingDocument, GlobalDocument, PresentationDocument, WebDocument, FormDesign, TextReportDesign, TextDocument, XMLFormDocument
Hey mahfiaz, Looked over your patch and think that as you have set it globally, you can remove all the module level entries for it. :D
Thanks to jphilipz's suggestion I also made a patch which adds the shortcut as global: https://gerrit.libreoffice.org/#/c/13332/
