In "marker view" I select some markers (holding Ctrl key). Then I go to "edit->delete special" where I tick Markers and press OK. What happens is selected markers are deleted (ok, that's what I wanted) and also ALL THE (unselected) MARKERS between them (disaster!). Any idea ?

Don't use the "Delete Special" function, use the DELETE key.

Thanks, of course ! (... I'm off banging my head on the wall)

Banging my head on the wall really helped because I have recalled that sometimes I want to CUT some selected markers and PASTE them elsewhere. Now imagine I have edited my thread:
 

Cut Special Selected Markers: is it a BUG ?  or was it intended ?   or am I doing sth wrong ?

Try this: In Marker view, ctrl-click the ones you want to cut. Then, click the little (-) sign in the upper left corner of the Marker view window.

And the forum come through again, stopping a perfectly good wall from being destroyed!

Tried. I guess (-) works same as "delete" button so this does not let me paste markers elsewhere.  
 

If I want to reposition a marker I drag to the new position on the timeline. 

id really like to see marker enhancements.
like copy markers with a midi file for example.
many times i back up my midi files, i would love to be able to copy marker info with it.
instead i have to create a blank project instead with just one midi track on it.
 
heyo, was up.
Chucks

I often need to do that with pitch markers if I change the song structure. I found out you can select multiple markers and drag them all at once.
