HELP! Accidentally changed settings!

Wolpi

When I typed the name for the next render my fingers accidentally slipped and hit some wrong keys.

Immediately almost all the shaders disappeared - fortunately in the render preview only, not in other windows or in the rendered result itself.

What change might I accidentally have occured in the settings to make any render preview look like that:

In the upper right corner of the Viewport, next to "Main Camera", there is a little globe...click on it and select Texture Shaded.

Thank you soo much for your quick and perfect help, dear mjc!
