Description

Describe the Bug

Enable space cadet shift - left shift (, right shift ) Enable auto shift

Quickly type shift-letter, and release shift before releasing the letter.

When using left shift, the ( will be before the letter. When using right shift, the ) will be after the letter.

If you release shift after releasing the letter, the () will not print, and the keyboard works as you would want.

Keyboard Used
