Some things i 've observed, so when i have grid in edit mode, deleting rows using popup menu works fine, but using shortcut not always.
Afther tests , it looks like , that it works ok when i run query and then select any cell from row using arrows (without mouse clicking), then ctrl+del work great. But if I select row# cell (because selecting other cells edits them) using mouse, it doesn’t work. Afther that , when I edit single cell and then using arrows move to another cell, it’s works again.
Ps. Why “select * from tab” can be edited, but “select * form tab a” not ?
