How do you use the hover over when developing with an iPad

Hello. My students are using their tablets, in particular their iPads, to develop apps in appinventor, but they cannot use the Hover Over component option. Apart from an external keyboard is there any other solution. Please help.

Exactly what event is this? (Button1.GotFocus...?)

I can't conceive of a way to hover a non-existent cursor over a block to get a tool tip popup.

However, component help is available from the Designer component palletes, in the form of (?) links after the component names.

Do iPads support multiple browser windows?
