Yes, there are plenty of keyboard commands you will need to use in the game. You can find the manual online. Heck, here's a post which will guide you there:

[Edit: again, this is for the original game. For MELE, I'd suggest getting it from the Origin client. Click the gear setting near the Play button, select game properties, and there should be a link to the manual?]
You can also see them in-game:
escape>options>settings>controls
Also, on first playthru, you should have tutorial pop-ups. If not, go to the in-game settings:
escape>options>settings>tutorials>reset tutorials (and make sure they are on)
