Not entirely. According to the session->track/bus->region hierarchy the
region selection follows track selection but not the other way around.

They will. :)

Could you explain? To me it depends on point of view and applies to both
regions and ranges.

I do...
Ok if you want. :)

Let's repeat that for ranges.
Selection - only if rightclick happened on range

Let's look at the functions contained within these submenus:


* play location
* play from cursor
* play from start

global functions. No changes here.

* play region
* play selected region
* loop region
* loop selected region

Region? Ranges are basically selections themseves and there's no
selection of range(s), no matter whether single or mulitple(at least

So we end up with:

* play range
* loop range

No (s) this time. Because we can only loop one range, the one we clicked


The entire menu makes no sense for ranges.

Note that 'Select all' as a global function should be available for both
regions and tracks.

is a definitive track based operation

all operations contained within this submenu are track based


* Cut
* Copy
* Paste
* Align
* Align relative

are definitely also range based operations, for both single and multiple
They belong to frequently used category, again, i wouldn't group them at

* insert region
* insert chunk
* insert ext. sndfile

are track based operations, can be grouped into 'insert'. 

* New region from selection
* Separate selection

range based operations, move to selection submenu.

And again, make the 'selection' submenu the main context menu. :)

Not really, all operations that work for a single region or a multiple
selection of regions can also work for all regions in a track.

Guess what? I have no idea :))
But i'd say no for now. track->region, not the other way around.
