Advanced tools greyed out and not available in Illustrator CC 2019

Same situation.  Switched to basic and the pencil tool became available.

Legally blind user here. Your directive to "read the documentation" is not kind or helpful. The documentation is not accessible. A very tiny icon is shown for the tool. The keyboard shortcut is not given in the documentation. For example, it says here in the offical docs to "Select the shear tool" with a horrible little icon that is not even retina-optimized so it can be zoomed without blurring: https://helpx.adobe.com/illustrator/using/scaling-shearing-distorting-objects.html. In fact, why does Adobe not use vector icons in its documentation? But more fundamentally, why is there no keyboard shortcut listed? Well, maybe its because there IS NO KEYBOARD SHORTCUT! You can hit S for scale, but not go into shear with the same key, like with other tools. Additionally, yes, they are grayed out in the selection menu... which is a terrible experience for visually impaired screen magnifier users who depend on menus because we just can't see the nuanced little Adobe icons well at all, and the user interface can't even be enlarged. So please be careful when telling people to just, "read the documentation," that directive does not show empathy.
