Let me test it now!

Pros and cons?

Unique about MathKeyboardEngine:

• it supports (almost?) all math mode LaTeX, including matrices. (Please share if you know anything that is not supported.)

• its syntax tree consists of very few different parts: the StandardLeafNode, StandardBranchingNode, AscendingBranchingNode and DescendingBranchingNode can be used for almost all LaTeX, including fractions, powers, combinations, subscript, etc. with ready-to-use up/down/left/right navigation.

• it can be used with any LaTeX math typesetting library you like.

A con:

• this library will never be able to handle setting the cursor with the touch of a finger on a typeset formula. (But it DOES support up/down/left/right navigation and has a selection mode via arrow keys.)

More pros:

• you have full control over what you display on the virtual keyboard keys and what a virtual key press actually does.

• customize the editor output at runtime: dot or comma as decimal separator, cross or dot for multiplication, cursor style, colors, etc.

• this library also supports handling input from a physical keyboard, where - for example - the forward slash "/" key can be programmed to result in encapsulating a previously typed number as the numerator of a fraction. (See the examples.)

• almost forgotten: it's open source, free to use, free to modify (please fork this repo)!
