Hello,
thanks for submiting the ticket.
If you have any suggestions for translations, you can attach them in a text file (English > Suggested translation), it would help us a lot.

Thank you very much.

Added the attachment with my suggestions.

In case of the translated DLC shortcut not fitting my only suggestion would be to do the same as in English version and abbreviate to first letter:

L SHIFT+P > Л.SHIFT+P

With punctuation mark for clarity, since it's all caps.

Iceman,
Was that enough information or is there any way I can be of more help to you in resolving this issue?

Mute - Заглушить
Vote kick - За исключение
Vote admit - За администратора

Killzone_Kid,
I was thinking the same for "Mute" at first, but stumbled in deciding on what would be a decent antonym in that pair.

What would you suggest for the opposite ("Unmute")?

In line with Killzone_Kid's suggestions, here are some alternatives. In case of "Vote kick", although informal, it is actually a more commonly used term among the players themselves:

Vote kick - Кикнуть (calque of the English "kick")
Vote admin - Назначить админом
Mute/Unmute - Заглушить/Дать голос (literally "Gag"/"Ungag")

Заглушить/Озвучить? Mute/Unmute

But probably Убрать голос/ Добавить голос is better or even better, Выключить голос/Включить голос

Vote admin - Предложить администратором?
Vote kick - Предложить исключить?

Imo functions like these should be icons, for universal understanding across the globe.

I agree,
The best case scenario would be the abstraction of common functions like these to iconic representations. Beside being universal on first sight, this would also solve the issue of screen space budgeting. Full descriptions can be provided as comments (mouseover text), with proper (non-Gamer) English as original, thus giving localization teams enough sensible context to deliver a more accurate translation.
