How can i change the black square caret to a normal looking caret ?

Hi @DungnvKaopiz,

A short answer:

latexConfiguration.activePlaceholderShape = '|';

A longer answer:

By default the LatexConfiguration uses a \blacksquare as activePlaceholderShape. You can change this to anything that your typesetting library supports. Both KaTeX and MathJax support the | character and this character looks most like the caret/cursor that is often used in texts. On most keyboards it is above the Enter key and shares the key with \.

I've updated the examples to use both the | and \blacksquare, depending on its position, like this (which is executed each time just before display):

if (keyboardMemory.current instanceof mke.Placeholder && keyboardMemory.current.nodes.length == 0) {
  latexConfiguration.activePlaceholderShape = String.raw`\blacksquare`;
} else {
  latexConfiguration.activePlaceholderShape = '|';
}

Note that also absolute values are entered with the | key. Therefore, you might want to also set the activePlaceholderColor just once at startup:

latexConfiguration.activePlaceholderColor = 'green';

Kind regards,
