There is no dedicated "Scroll Lock" button on this model.
The function is not directly available on this keyboard or can only be used via alternative key combinations or software (e.g. Logitech Options+).
No, the pictures on Digitec/Galaxus are wrong! It is a normal CH keyboard layout with the "M" key in the second bottom row to the right of the "N" key.
The keyboard from the Signature Slim Combo MK950 can generally be connected to an iPad via Bluetooth, as it supports Bluetooth and does not require any special software for the basic functions. However, the mouse does not work with iPadOS, as Logitech mice are generally not compatible with iOS/iPadOS. The advanced functions such as button assignment or switching between devices via Easy-Switch are not available on the iPad as the Logi Options+ app does not support iPadOS.
The Logitech Signature Slim Combo MK950 uses batteries as its power supply, not rechargeable batteries. The keyboard and mouse in this set are equipped with replaceable batteries.
It is possible that the keyboard setup is in "Mac" mode - to switch to Windows (PC) hold down the Fn and P keys for 3 seconds (Fn and O to return to Mac).
