| Formatting | Code | Looks like |
|---|---|---|
| plain text | \text{text Pr} | \(\text{text Pr}\) |
| bold Greek symbol | \boldsymbol{\epsilon} | \(\boldsymbol{\epsilon}\) |
| typewriter | \tt{blah} | \(\tt{blah}\) |
| slide font | \sf{blah} | \(\sf{blah}\) |
| bold | \mathbf{x} | \(\mathbf{x}\) |
| plain | \mathrm{text Pr} | \(\mathrm{text Pr}\) |
| cursive | \mathcal{S} | \(\mathcal{S}\) |
| Blackboard bold | \mathbb{R} | \(\mathbb{R}\) |
