@Caefix reported that this port has issues with the zoom keys not being in the keymask.

It likely has a 2 stage zoom lever. I don't see any zoom keys defined in the source from https://chdk.setepontos.com/index.php?topic=13426.msg139691#msg139691 but I'm not sure if that's the latest.
Don't forget what the H stands for.

Happy New Year to everyone!  :xmas
Yes this is the last source, sig_finder missed the ZOOM keys and I didn't find anyone with the camera to look at it.

Understood, maybe @Caefix can do this test https://chdk.setepontos.com/index.php?topic=13355.msg142207#msg142207
physw_status is 0x0001a278

Also, should I add the current source to trunk with autobuild disabled?

I think it could be added, if there were major issues, probably someone would have reported it already.

:o :-X zoom keys adjust address, default step in memory browser=4, I would need 0x0001a278 /4 keystrokes to reach it. Poor cam... :(

BUGT   :)  You could do a special build with preset 0x0001a278 in mb ?

Edit: As a first approach, we could try the same offset as Sx610? (Maybe same order in keymap)
Edit2: I´ve read some keymaps. The steps are either 0x04 or 0x08. That seems the only common sense.
         Zoom keys can be ie 0x30 away. :-[

When you load this version in your camera, you'll see something like this.

MEM: 0x1e3c1e3c
PS1: 0xffdf9
PS2: 0
PS3: 44003f4


This will display the 3 words of physw_status[].

Do not press any key.
Write down everything you see in the display. and send me those values.

Then press the ZOOM buttons one by on and note which of the 3 words show a change (each button will affect one bit). Write down the values you see when some of the buttons are pressed, send to me and this value and make a note for which button applies.
ZOOM probably has two speeds on that camera.
For example:
"When I press a ZOOM_IN low speed, PS3: 0x44003f4 was changed to PS3: 0x44001f4."
The values you will see will surely be different.

 8) First anwsers.
no keys:
MEM: 0xeeeeeeee
PS1: 0x??????73
PS2: 0x705c00?d
PS3: 0x3294fefa
keys don´t work in playback.

now lens open

MEM: 0xeeeeeeee
PS1: 0x??????73 // same 7 ??
PS2: 0x7#dd0??d // the 7 is unstable
PS3: 0x3294fefa

left out: unst. 7 --> unstable 3 
right out 7 stable.
# could be related to zoomposition.

PS3:
"up" -> defa
"down" -> 7efa
"left" -> eefa
"right"-> befa
"set"  -> f6fa
"menu" -> 7cfa
"video"-> fafa
"play" -> fe7a
"shoot/2" fe72
"shoot"-> fee2

The word PS3 doesn't change if you move the zoom lever?
You can try this build, but it's a pure speculation for the zoom keys.

EDIT: test build removed
