In Sonar 7 and 6, when I select all the markers in Marker View and copy them, nothing gets into the clipboard that Word is able to recognize: the Paste and Paste Special items are completely grayed out. Nor can markers be pasted into a Notepad txt document.
As far as I can tell, the only way to copy marker names is to open each one, copy it, switch to Word (or whatever), and paste it. Repeat. Lots of tedious clicking and switching. (At least the marker name is already selected when the marker is open.)
If you have a lot of markers, you could try taking a screen shot of Marker View, and then running the image through an OCR program to convert it to text. Is it worth it?
It should be possible to copy markers as text, and also to export them as a separate text file. It should be possible to then import those marker files back into the project and into new projects. Same with regions... except Sonar doesn't have regions....
