| "Set input method to `racket-unicode`. | ||
| The `racket-unicode` input method lets you easily type various | ||
| Unicode symbols that might be useful when writing Racket | ||
| code. | ||
| To automatically enable the `racket-unicode` input method in | ||
| `racket-mode` buffers use `M-x customize-variable <RET> | ||
| racket-mode-hook` or put the following code in your Emacs init | ||
| file: | ||
| (add-hook 'racket-mode-hook #'racket-unicode-input-method-enable) | ||
| Likewise for `racket-repl-mode` buffers: | ||
| (add-hook 'racket-repl-mode-hook #'racket-unicode-input-method-enable) | ||
| To temporarily enable this input method for a single buffer you | ||
| can use `M-x racket-unicode-input-method-enable`. | ||
| Use `C-\\` to toggle the input method. | ||
| When the `racket-unicode` input method is active, you can for | ||
| example type `All` and it is immediately replaced with `∀`. A few | ||
| other examples: | ||
| omega ω | ||
| x_1 x₁ | ||
| x^1 x¹ | ||
| |A| 𝔸 | ||
| test-->>E test-->>∃ (racket/redex) | ||
| To see a table of all key sequences use `M-x | ||
| describe-input-method <RET> racket-unicode`. | ||
| If you don’t like the highlighting of partially matching tokens you | ||
| can turn it off by setting `input-method-highlight-flag' to nil via | ||
| `M-x customize-variable`." | ||
