UEB, Nemeth & Braille input

Use supported mathematical Braille output and input alongside the ordinary expression editor.

Find it

Graph settings → Display → Braille code; expression row → Braille controls

Try it step by step

Choose UEB or Nemeth and Apply.
Read or copy the expression’s Braille output. Select Unicode or BRF as needed.
Open the input controls and paste Braille, or enable six-key entry.
Review the translated mathematical preview before applying the input to the expression.

UEB / Nemeth: Select the mathematical Braille code that matches your material. The same dot pattern can mean different things in the two codes.
Unicode / BRF: Unicode uses Braille characters; BRF uses its ASCII representation. Use the format expected by your workflow.
Six-key entry: F, D, S enter dots 1, 2, 3; J, K, L enter dots 4, 5, 6. Press a chord and release it to enter a cell.
Input preview: Check the translation and diagnostics before applying. Invalid or unsupported notation is kept explicit.
Dot picker: Toggle dots 1 to 6 and choose Insert cell if six-key entry is inconvenient.
Apply / cancel / reload: Apply Braille commits a valid preview. Cancel leaves the expression unchanged. Reload from equation refreshes the draft; a changed source blocks applying an obsolete edit.
Download / retry: Download Braille text or BRF. Retry Braille translation if loading failed.
Piecewise branches: The structured editor lets you work on conditions and branch values separately.
Coverage: Supported fractions, powers, comparisons and other structures are translated; this is not a guarantee for every Braille convention or device.
