Modernflyouts: Show message when you turn on / off the Keyboard brightness

[Sav22999]

Show a message also when you turn on or off the Keyboard brightness

[Samuel12321]

do you mean keyboard backlight brightness controlled by function keys (for keyboards that have a backlight)?

[Samuel12321]

if so there are some issues with this #57 due to most keyboards embedding this control in firmware.

[Sav22999]

@Samuel12321 Actually many keyboards (also mine) don't use Fn button for shortcuts, so you just need to press the relative button, without Fn.

But, anyway, if you got some issues, it's not a problem, it was a suggestion to improve this amazing project :smile:

[Samuel12321]

always looking for suggestions 😉.
just out of curiosity, what is the output when pressing that key while on this site http://keycode.info/ , it is possible if it is software controlled.

[Sav22999]

Nothing :confused:, but also Volume, Display Brightness don't return anything...

[Cyberdroid1]

But then how is it possible to be controlled in Bootcamp Windows on an Apple computer? There is even a software window popup for that. Maybe exclusive, I don't know.

That's how it works. This is the reason it is non-trivial to detect them. It's not possible for us to do anything regarding this

[ShankarBUS]

@Cyberdroid1,

I don't understand. Can you elaborate your statement?

[Cyberdroid1]

When we run Windows on an Apple Computer like a Mac, we use a utility called BootCamp by Apple. It is like a special control panel that controls various Mac-only features. That software is able to detect Keyboard brightness keys and also shows a UI window for the same.

[Cyberdroid1]

We get a UI like this in lower bottom

[Cyberdroid1]

@Sav22999
Assuming you are on a laptop, this setting can be changed by going into the BIOS of your laptop and changing "Action Keys" or something related to Off.

[ShankarBUS]

Is BootCamp a VM? Or a boot manager/OS installer for other OSes on Mac?

If it's not a VM how could it show a UI from macOS over Windows?

Does that add some special tools (i.e drivers or softwares) to Windows while installing it?

[ShankarBUS]

There are no concept of Brightness/Airplane mode/Fn keys on any OS. They are not passed as keys but as hardware signals (which the OEMs decide). That's the issue here. Any OS can receive those signals if they have the required driver. Even some Linux and Android distros can show brightness and airplane mode popups.

This is the hard part.

[Sav22999]

Oh, I've understood. Thanks anyway

BootCamp is utility software by Apple which allows running Windows on a Mac computer. It adds special software to create a link between both macOS and Windows.

Does that add some special tools (i.e drivers or softwares) to Windows while installing it?

Yes, it adds some special drivers to Windows

[ShankarBUS]

Closing this issue as it's invalid and literally impossible to implement.

[ShankarBUS]

@Sav22999,

Does it look like this?

If you don't mind could you tell me what laptop you have or post photos of your laptop?

If you really want to see this implemented, I need to check if the message is actually received by Windows.
I need your help 😅😁🙏.

[Sav22999]

Similar to it.

[ShankarBUS]

What are the other keys? Could you post a pic of the whole Fn keys? (just for research purposes? 😅)

[Sav22999]

Sure

[Riajyuu]

Just a question from curiosity: for most plug-to-use keyboard, brightness adjustment command won't be responded on OS level but on keyboard firmware. How can that be supported then?

e.g.

My keyboard uses right Fn + ↑ or ↓. Windows does realize I press those keys but doesn't understand what they mean (unless any app register that combination).

But it is possible indeed to allow users to set customized combination and message, like:

Keyboard combination: right Fn + ↑, display message: keyboard brightness up.

[Samuel12321]

keyboards don't often actually send windows the FN key pressed command
