In a data grid or a result grid from a SQL Commander tab, the Jump To Quick Filter key binding moves the cursor to the Quick Filter field.
That keystroke should do the same thing when the Row Form window is displaying a individual row from a grid (see attached picture).
[Ctrl+Tab can be used to move between Quick Filter, the grid, 2 "invisible" fields and the Close button, but that's a lot of work to do to jump to the only field on the page that the user wants to type into!]
Thanks. We will look into this.
