Thanks for the response.
I forgot to mention I also tried sending [TAB] as keystroke.
I'm an experienced customiser of Strokeit but this is a behaviour I haven't met before.
There's not much to see at the config file, right now there's the series of temporarily disabled commands mentioned i.e.
Keys - Hotkey, Hotkey: TAB
Keys - Send keystrokes: [TAB_DOWN][TAB_UP]
Keys - Send keystrokes: [TAB]
WinMsg - Post Message, Send To: Current (also tried title match), Message ID: 0x0028
WinMsg - Post Message, Send To: Current (also tried title match), Message ID: WM_NEXTDLGCTL
preceded by a Windows - Active Window by caption & pattern match ticked. Which is redundant really because I have another chain of commands from a previous strokeit action landing there and typing a few digits on that very text box I can't escape from. Alas I just wanted to make sure the focus is still there.
By the phrase quoted I meant that the horizontal tab character (HT) is inserted into the text field instead of shifting the focus to the next control box.
I should mention it does work as expected when using the keyboard tab key. Each time the tab key is pressed, the focus jumps over to the next box of the form.
