When you have finished answering a question and submitted it, HOW do you return to the question list?

here is how you answer a question without losing your place in that ridiculous continuous scroll

do not click on the link to open the question

instead, hover the mouse pointer over the question's link and click on the MOUSE WHEEL, not the right or left mouse button

this automatically opens that link/question in a new window without bumping you out of the window you are viewing, the one with the continuous scroll

click on the tab to view the window, answer the question and hit Submit - it will automatically put you back to the top of the list of Open Questions for that category - IGNORE that and simply close the tab/window by clicking on the X

(clicking on the mouse wheel while the mouse pointer is anywhere in the tab will also close the tab)

the window/tab closes and you are looking at the Open Questions in EXACTLY the same place on the scroll

basically because you answered the question in a completely separate window, it will have no effect on the continuous scroll

you can also open the link in a new window by clicking on the link with the right mouse button and clicking on 'Open link in new window' in the drop down menu but using the mouse wheel does this in one quick step

You don't use the back arrow. Scroll to the top of the page to click the category you were just in when you answered. And all the categories listing open questions are all on the left.

the back button or just open the question in a new window/tab from the question list
