Perhaps something new for chdk 1.3?
I would say, it would be something nice to have with quick access.

May be this can be added to the chdk menu in the future. For now using Zoom Value to [ EFL ] somehow helps.
So how would this work? 

You set a Zoom EFL Value in the menu,  and CHDK pauses every shooting process to make sure the zoom lens is adjusted?  And nobody will complain about the 1-4 second delay after they push the shutter button?  (a new standard for shutter lag).   

Or does it adjust the zoom as soon as you change the value in the menus?  What happens if you are still in playback mode? And does it only do this once when you set the menu value?  Or does it reset the zoom to the desired position regardless of where you try to set it via the zoom lever ?

Hopefully I'm missing something,  but how to implement this and not make it a PITA escapes me.

I think the best way if done, perhaps would be from
a lua script that you can have in the user menu. In my case,
I always keep an eye on Zoom Value (EFL) if I want the
same field of view. And yes, it is slow no matter which way it is done, the zoom is sloooow :)

(snip)

(snip) why would you want to set it from the CHDK menu (snip)

Just to start the camera at a certain zoom step which is always the same. And that I want the camera to keep. (snip)

On the SX50 you have Custom 1 and Custom 2 which are built into the camera. (C1 and C2 respectively on your dial). They recall focus and zoom, in addition to numerous other settings. It's pretty diverse. For example, you can set C2 to be HQ mode, zoomed to a certain level, manually focused just so.

In camera mode set mode and functions you want to save; also zoom and manual focus. Now press Menu, Save Settings..., and destination C1 or C2.

However, you seem to want more than two settings. My advice would be to look at the markings on the top of the lens. While only a rough guide you should be able to learn where each 35mm equivalent is, approximately, but looking down on your camera and zooming it there.

It would indeed be nice at some point to see extra custom settings added, ideally where you could name them.

Yes, I know about  Custom 1 and Custom 2.
But what I am looking for  is a way to save different custom settings into files from chdk, and place them on the user menu. Something just like Custom 1 and Custom 2...

That would require an upgrade to the CHDK User Menu code.   There was a long discussion about this last year - the forum thread picks up right about here : http://chdk.setepontos.com/index.php?topic=8151.msg88472#msg88472

However, AFAIK, a Lua script can read & write files on the SD card so writing a script to save any current values of interest should not be hard.  Reloading those values using a second script would also be easy.   If you put the script name in the User Menu  ( e.g. Custom1.lua , Custom2.lua ..)  then you have a two step process that can work - load the script from the user menu, exit the CHDK menus, and press the shutter button to load the config settings file associated with the script.
