How Do I Delete A Character

[Erinville]

Technomate TM Twin OE

I have put in too many characters in my wireless WiFi set up on my Technomate TM Twin OE.
I have 2 too many.
How do I delete these extra characters?

Use the arrow buttons, usually either side of zero.

Many thanks for that. It worked a treat.
