I'm new to writing constraints for generic items in Bann.

Suffice to say that the Text Editor provided out of the box is wanting.

Is there a third party editor one can use?

Thanks in advance.

External editor could be used (notepad). It is necessary to set it up for text group you use for constrains. (tttxt1116m000 in baan IV, tttxt1110m000 in LN, not sure about session code for baan 5)
Editor by text group is company related, so do not forget to set up in all companies you need.

tttxt1110m000 session is available to use. I've launched the session and I'm able to change to a different editor. Now I'd like to add "TextPad" to the list of External Editors. How do I do that?
