Is there an easy fast way to move from the end of a batch with many entries back to the first entry?
Yes - click in any field then use CTRL + <-- (CTRL key plus back arrow - on Windows OS - hold <-- down to repeat). You will see the Entry x of y (blue bar above Entry fields) decrements quickly.
Working on a chromebook. So this didn't work?
I apparently did not understand the question. I use the method described below by AThayneGreen
I think if you have selected an Entry field it should work. You can check keyboard shortcuts under Help menu. I'm not using chromebook but unaware that this wouldn't work on it - perhaps Chromebook needs 'special key' in addition to Ctrl? Here is a Chromebook shortcut list (it appears Ctrl+<-- is defined otherwise):
Just enter 1 in place of x in the "Entry x of y" and hit the Enter key. You can go to any entry number this way.
