#52 Assigning non default custom class poorly accessible

[Avneesh Singh]

Assigning custom class with non default name has poor accessibility for keyboard user.

steps:
1. In a project move focus to an audio block.
2. Activate Blocks menu and open assign role submenu.
3. Move down to last menu item i.e. assign custom class in this submenu with keyboard.

Result: Arrow keys of Keyboard is stuck in textbox provided to enter custom class name. One can jump ahead only by using tab key.

comment: Testbox should not lie in drop down menu as it makes keyboard navigation difficult.
