Thank you for your post.
Modifier keys, arrow keys, and non-printable characters are currently unavailable under iOS. At this time, FileMaker Go cannot read the iOS keyboard.
Hi TSGal and thanks for the clarification.
Are there any workarounds?
What modifier key were you hoping to catch? Shift key? You can always use the Code() function to see if the value is between 065 and 090, as this would signify an uppercase alpha character.
