These keyboard shortcuts in Practice sets are only functional when focused on a math input field or a related widget, such as the onscreen math keyboard or the button that toggles its appearance. However, the shortcuts will not work if they interfere with the keyboard accessibility of the related widget.

LaTeX-inspired shortcuts
The following key sequences are based on their LaTeX commands without the preceding backslash ("\").
- Greek letters: Most lowercase and many uppercase Greek letters can be spelled out and will transform into the corresponding symbol. For example, typing "alpha" will produce "α".
- Common constructs:
- "sum" and "prod" transform to summation and product sequence, respectively.
- "int", "iint", "iiint", "oint", "oiint", "oiiint" transform to various kinds of integrals.
- "frac", "sqrt", "lim" introduce fraction, square root, and limit, respectively.
- While not strictly LaTeX, the following constructs also work:
- "root" will insert a root with a root-index.
- "ceil" – ceiling operator (⌈...⌉)
- "floor" – floor operator (⌊...⌋)
- "norm" – norm operator (‖...‖)
- Most named operators:
- "sin", "arcsin", "sinh", and other trigonometric functions
- "min", "max", "det", "exp", "log", "ln"
- Operator symbols:
- "nabla" (∇), "partial" (∂), "times" (×)
- "angle" (∠), "degree" (°), "triangle" (△)
- "forall" (∀), "exists" (∃), "nexists" (∄)
- "parallel" (∥), "nparallel" (∦)
- "in " (with a trailing space) produces "∈"
