UI - keyboard Enter for OK!

I very often press the supported “E” key (exercise?) while riding to pull up the workout menu during a session. Normally, my workout is pre-selected before I ride, but often I don’t want to immediately enter workout mode. However, to accept a selected workout, I MUST use the cursor control keypad (mouse etc.) to select OK. One should be able to simply press the Enter key to accept the workout displayed. It’s difficult to locate the position of the cursor, then move it accurately to the OK emblem whilst riding, not to mention a waste of time. Being able to press E, followed by the Enter key would facilitate much more rapid confirmation. This is a nearly universal keyboard action in all application software. The fact that it’s not present in Zwift is quite frankly bizarre.
