Even with an English keyboard (a UK-English, not US-English, that is!) it's difficult enough at times!
For 1x time compression, I have to press the '\' key, which for me is in the lower-left, between the left Shift key and the 'Z' key.
Furthermore, for 'All Stop', I have to use the ' (apostrophe) key, which is two keys to the right of 'L'. It should be the key under escape, which is '~' on US keyboards, but not on UK...
Here's a typical UK-English keyboard for reference:

You could set two keyboard layouts in your Windows regional settings section. Then you can switch between them with Alt-Shift. If you set it to US-English before you start the game you should find that the keyboard commands match the in-game F1 key chart. I don't bother myself, but should work
