Personally, I use number-format for units. Not all locales follow the pattern of ${number} ${unit}

The German texts sound a bit strange. There are informal texts like "Finde …" or "Setze …" and formal texts like "Verwenden Sie …". I always try to avoid this decision by using words that don't need it (mostly infinitive). Here are my suggestions:

"GeolocateControl.FindMyLocation": "Meinen Standort finden",   // or: "Aktueller Standort"
"NavigationControl.ResetBearing": "Orientierung auf Norden zurücksetzen",
"ScrollZoomBlocker.CtrlMessage": "Zoomen der Karte mit gedrückter Strg-Taste",   // makes clear it's a key and avoids jargon like "+"
"ScrollZoomBlocker.CmdMessage": "Zoomen der Karte mit gedrückter ⌘-Taste",
"TouchPanBlocker.Message": "Verschieben der Karte mit zwei Fingern"

I'd also suggest changing these English texts:

"ScrollZoomBlocker.CtrlMessage": "Hold the Ctrl key while scrolling to zoom the map",
"ScrollZoomBlocker.CmdMessage": "Hold the ⌘ key while scrolling to zoom the map",

Thanks for the contribution, @ygoe!

@melanieimfeld, @kkaefer, what do you think of these suggestions? #11733 (comment)

Glad to see this is happening.

I support a customer who does Indonesian and Transitional Chinese (HK, TW) which aren't in this PR.

The translations we are using came from Lionbridge and differ a bit from those in this PR, not sure if you're interested in seeing those differences?

[stepankuzmin]

Hi @andrewharvey,

Yes, we already have PRs for Indonesian and Tranditional Chinese that needs to be verified, any contributions are welcome!

Verifications are still needed for Czech, Greek, Indonesian, Georgian, Malay, Norwegian and Norwegian Bokmål, Slovak, Slovenian, Thai, and Traditional Chinese.

I wonder if "Improve this map" could also be translated? So far I haven't seen any option to achieve this. Is it possible?
