* Ctrl-G Works on some Windows systems (depending on graphic driver)

* MAC Cmd+A overrides standard “Select all text in current text box”, might possibly be able to change to Ctrl+Cmd+A in next version.

* Spacebar Drops Marker at current GPS position NOTE: This must be enabled by manual edit of the opencpn.ini file. [Settings] …”SpaceDropMark=1”, to activate this feature. [Settings] …“SpaceDropMark=0” deactivates the feature.

NOTE: This list may not be completely detailed and correct for now, but it does try to establish all the shortcuts available.

We may need to add some things to Caesar's Functional and tabular list to make it more complete. Please contribute ideas and corrections/improvements!
