Capturing keystrokes: Alt, Up Arrow, Down Arrow

[Turtle Trader]

Hello,

This is obviously not a supported NT feature, but perhaps one of the guru guys will know...

I have an indicator that is watching for certain keystrokes via the KeyDown and MouseDown events, and it is working fine.

Except, I cannot see the following keys:

Alt
Up Arrow
Down Arrow
Right Modifier keys (Shift, Alt, Control)

I suppose that they are being gobbled up by Ninja and not passed through?

If anyone has a solution, thank you!!

Hi Turtle Trader, you are correct, not an officially documented item however for some ideas you might want look into this implementation from the sharing, it would for example work via accessing the Alt / modifier key inputs. Works as expected on my side.

Ok!

Hi Bertrand,

Thank you.

that works really good for catchting the ALT key in the mouse event

I'd also like to catch the Up and Down (arrows)....do you have any samples?

Turtle Trader, was able to get something together which I feel should be beneficial. Please check into the attached example borrowing a bit from the earlier one I pointed to. The key is working with the PreviewKeyDown as documented here on MSDN -

Thank you Bertrand! That is going to be really helpful.

Hello leontancfa,

I'm not able to find the pages that were linked.

I was able to find a post that uses modifier keys. This one is looking for alt.

The Microsoft documentation linked also has an example of this for the Shift key.
