Highlighting inputs textarea

[3goats]

High is there anyway I can highlight a bound input textarea ? e.g.

 <textarea contenteditable="true" bind:value={operationsDoc}></textarea>
 

I don't need a full blown code editor here, just the ability to update a couple of values in the highlighted text before I send it to an API.

I have also wanted this feature as the other alternatives just are too complex and I need to add additional packages.
