🙁 CanÂ´t change to alt.
Looks, like only zoomkeys are working, have I missed the joke? 🤣

O.K.
Don't use that anymore.

Do you use chdkptp?

😐: No way, see Ixus275.

Please, just spell out whatever you are trying to say as clearly as you can.

🙁 Here we are digging for &zoom_key.
Build with recently improved memory browser could help.

Build with recently improved memory browser could help.

You can get the memory browser module from any non-DIGIC6 release you find on this page. For example, A1000, right at the top. The file is named memview.flt, it's in CHDK/MODULES. Copy that file to the same directory on card. With the new module, you can adjust the increment by half pressing the shutter.

😁 Thx!
right/2 -> f973
left/2 -> f573

btw: Blackholes optional console seems to use something like
"sprintf(string, "Img_%4d",get_exposure_counter());"
Img_%04d was better readable, (%02x, I know...)

Edit:
0x0001a284
right /2 0x0008 0c00 -> 0x0008 0800
right out 0x0008 0c00 -> 0x0000 0c00

left out 0x0008 0c00 -> 0x0008 0c00 ??

I don't understand what this means.

Edit:
0x0001a284
right /2 0x0008 0c00 -> 0x0008 0800
right out 0x0008 0c00 -> 0x0000 0c00
left /2 0x0008 0c00 -> 0x0008 0400
left out 0x0008 0c00 -> 0x0008 0c00 ??

From this it follows that ZOOM_IN is 0x400 and ZOOM_OUT is 0x800, but you had to see it in the first word at 0x1a278 ???
I assume you pushed the zoom lever all the way, to the both sides, which should be a fast zoom speed.

Attached is a test build

I made a mod to the physw debug helper. It shows the 3 words bit-by-bit, should make button identification much easier. Bits are shown as their value in the hexadecimal digit, a "ruler" is displayed at the top to make evaluation easier.
Patch and screenshot attached.

Test build with modification from srsa's post.
In the memory browser, select address 0x1a278, press PLAY to exit ALT mode.
Pull the zoom lever all the way in, and watch the changes in MEM and PS1.

😀 The viewable change is PS1: pos "5." [08>>00]. (right out)
MEM line still jumping because of a missing 0 in a "%2x".
left out is clear to see in PS2, pos"..".7 [04>>00].

Looks like the "ruler" is ambiguous. 🙁
I'd guess the first number is 0x00080000, the second is 0x40000000, because of the following lines in physw_bits.txt (file created by the sigfinder)
[tt]levent 0xffffffff, 0x00080000, index 0
levent 0xffffffff, 0x40000000, index 1[/tt]

PS1 the "...7" byte changes 0000..0021, followed by 0000 0000.

Do you see in the memory browser at 0x0001a278:
DWORD: xxxxFD73
WORD: FD73
BYTE: 73

You wrote earlier:

0x0001a278:

right/2-> f973 //Zoomlever pressing right, half way (_in)
left/2 -> f573

<--> zoom/2 work fine now, zoom full disturbs firmware.

At 0x0001a278 you see PS1,not PS3
It means:
right/2-> f973 0xFD73-0xF973 = 0x400 { 0, KEY_ZOOM_IN ,0x00000400 }, //half

left/2 -> f573 0xFD73-0xF573 = 0x800 { 0, KEY_ZOOM_OUT ,0x00000800 }, //half

Can you confirm that the ZOOM keys works fine in ALT mode if you do not push the zoom lever all the way?

Looks good to me on the sx410.
Judging by the image from the post above, he can see the required bits in the MEM line.

See if you see a change in the MEM line if you move the zoom lever. Watch last 4 digits (fd73)

Caefix

MEM line still jumping because of a missing 0 in a "%2x". in pos "fd" :😀
r/2 fd >> f9
l/2 fd >> f5

More bits &tomorrow...

Bit generator reactivated....
No visible changes in fd73. Was a logfile possible here?
Edit: btw. logged ubtest.bas with CurrentPrivateUbasic peeking for &PS1 all keys show xxxx fd73.
