An APL palette for on-screen "typing" of APL chars
If you have a need to type APL into the J session or an IJS window, the following script might help you.
It shows a palette of APL chars, plus some extended Roman letters and a few miscellaneous symbols.
This is the screen appearance:
Click a char to make it appear at the current selection in the J session or IJS window.
Warning: it works by placing the char on the clipboard and then sending a "Paste" message. So you will lose clipboard contents.
