Assessment: Shortcut to add manual feedbacks in the assessment editor

[chrisknedl]

Is your feature request related to a problem?

As far as I know, you always have to click on the little + icon in the assessment editor to add feedback. In cases where many feedback items are necessary, always having to switch between mouse and keyboard can interrupt or slow down the workflow.

Describe the solution you'd like

Add a keyboard shortcut to add inline feedbacks. For example, when the cursor is in line 10, click the + on the keyboard to add a new feedback item on that line.

Describe alternatives you've considered

Different shortcuts with more than one key, if only + is pressed too often accidentally.
