+`Julia` allows the use of *Unicode* symbols to replace variable names and for function calls. Unicode operations are entered in this pattern `\name[tab]`. That is a slash, `\`, the name (e.g., `alpha`), and then a press of the `tab` key.
+
+
+In these notes, the following may appear as variable or function names
+
+
+| `\Name`  | Symbol | Usage notes                     |
+|:-------- |:------ |:------------------------------- |
+| `\euler` | `ℯ`    | The variable `e`                |
+| `\pi`    | `π`    |                                 |
+| `\alpha` | `α`    |                                 |
+| `\beta`  | `β`    |                                 |
+| `\delta` | `δ`    |                                 |
+| `\Delta` | `Δ`    | Change, as in `Δx`              |
+| `\gamma` | `γ`    |                                 |
+| `\phi`   | `ϕ`    |                                 |
+| `\Phi`   | `Φ`    | Used for parameterized surfaces |
+| `x\_1`   | `x₁`   | Subscripts                      |
+| `r\vec`  | `r⃗`   | Vector annotation               |
+| `T\hat`  | `T̂`   | Unit vector annotation          |
+
+
+The following are associated with derivatives
+
+
+| `\Name`    | Symbol | Usage notes                 |
+|:---------- |:------ |:--------------------------- |
+| `\partial` | `∂`    |                             |
+| `\nabla`   | `∇`    | del operator in CwJ package |
+
+
+The following are *infix* operators
+
+
+| `\Name`  | Symbol | Usage notes   |
+|:-------- |:------ |:------------- |
+| `\circ`  | `∘`    | composition   |
+| `\cdot`  | `⋅`    | dot product   |
+| `\times` | `×`    | cross product |
+
+
+Infix operators may need parentheses due to precedence rules. For example, to call a composition, one needs `(f ∘ g)(x)` so that composition happens before function evaluation (`g(x)`).
