When I press the N key for properties in the latest 2.8 alpha 2 in the top right viewport window, I loose the preview. Try it!
In the blender 2.8 manual, it says to press the E key in timeline etc to set end frame to selected point (just like 2.79) This and the corresponding S (for start) don’t seem to work. Have the keys been changed? Is the manual wrong?
