On blocks.wp-a2z.org the Dashboard menu scrolled instead.
In Erica’s video she demonstrated moving blocks by clicking on the move up / move down then using the cursor to move the block. This doesn’t work on an iPad with an attached keyboard.
Once the blocks toolbar has focus then the left and right arrow keys may move through the tools, showing what they do. There’s no Escape key. Leaving a drop down menu requires you to click elsewhere. Sometimes the drop down menu doesn’t go away.
