I am hoping that someone with more experience than I can provide a quick example of how to create a simple palette.
I know I should read the documentation to do this, but a simple working example is all I need.
I'd like to be able to select text from within a text cell, and then have a palette button replace the selection with a Hyperlink to the documentation.
For example, if the word HistogramList were selected, then that selection would be replaced with a ButtonBox:
ButtonBox["HistogramList", BaseStyle->"Link", ButtonData->"paclet:ref/HistogramList"]
and then I would install this as a palette for later use.
