Currently I can't delete all selected keys in Dopesheet (translate, scale, rotate keys etc). When I draw a box over all keys in Dopesheet, I can only delete some keys, not all that I've selected. That wasn't a problem in previous versions, it started from 1.011 or so

Thanks for the bug report. Reproduced and will be fixed in next update.

Oops, that is not good. Fixed in 1.0.16, available soon.

This is also applies to Cut function

1.0.16 is up, this is fixed for delete and cut.

Cool, Thanks
