TIP :

there is a quick way to typ numbers (and other SHIFT-accessable digits) on iPad in iOS12 and iPadOS :

when the on-screen keyboard is visible, just swipe-down (pull-down) on the on-screen key to get it’s SHIFT-version

e.g. : if you swipe down the 3-key, you will typ the #-sign, and if you swipe-down the 7-key, you will typ the &-sign

enjoy 😉
