DataGrip editor has command ⌘-/ to "Comment with line comment", in SQL that means adding -- to beginning of line.
On my MacBook Pro with Finnish keyboard, / is located in shift-7. When I press ⌘-shift-7, DataGrip opens search box in Help menu or flashes Code menu title, instead of commenting current line. Selecting "Comment with line comment" from Code menu works as expected.
Is there a keyboard shortcut that works on my keyboard?
