Due to the unavailability of a Mac OS based machine we are not able to verify the correctness of the MacOS "keyboard shortcuts" for NvuHelp. We need to know if any of the keyboard shortcuts have been wrongly documented. As NvuHelp is packaged in Nvu 0.60, the current keyboard shortcuts as documented right now are available in it.
If you have a MacOS based machine and are interested in helping please check if all the keyboard combinations work for you or not. If there are errors, write down the command and the correct keyboard shortcut combination and send the list to me.(Email at "kdsDOTsahambiATgmailDOT com" or just add the list as a comment to this post.)
