This is quite annoying when you want to, e.g., indent the whole file (or apply some other function) and then want to continue to work on where you were before. How can I select the whole buffer content without jumping the the first line of the buffer?

At the Elisp programming level, Emacs provides an assortment of features for this, such as "save-excursion" and "set-window-configuration." I don't think there are any direct bindings to these functions (can anyone prove me wrong?), but I've used the below code, in my Preferences.el or equivalent for ages. This makes C-u C-M-z save the current window state, and C-M-z restore the previous state. So you can for instance do some sequence like this:
>  C-u M-C-z (save state)

>  M-q (indent region)

If all that elisp is too daunting, you could use a register to remember your position.
(It scares the b'Jasus out of this Emacs newbie)

C-x r <spc> 1 will remember point in register 1
C-x r j 1 will get point back where you left it.

But thanks Jack for that code. I didn't know about pushing and popping your whole window configuration. I really must get my head round elisp.
