[NTG-context] [OT] Mini-keypad for typing math symbols

https://www.crowdsupply.com/summa-cogni/mathpad This might be of interest to some. I have no affiliation with the developer. It's a specialised keypad that sits alongside your normal keyboard and provides rapid access to 112 mathematical symbols and Greek letters, saving the need to hunt around in fiddly character viewers. It's switchable between Word, OpenOffice and LaTeX — Bruce Horrocks Hampshire, UK
