I have been frustrated for a while (Release 8 and 9) when working in the LotusScript Editor for Web Services. None of the new Eclipse style Preferences or tooling features work in that editor. It seems to be a legacy version of the agent editor. It is pretty much the same editor experience as the button script editor when you add a hotspot button in rich text within Notes.
It is missing Features like
control of Fonts
control of Line Numbers
Color printing
Color paste to rich text
Modeless Find/Replace dialog
...Probably a few more, as this editor appears to be the legacy R5 era editor.
But there is hope!
- I just found that a Right-click while in the pane at least allows you to change the font using the Programmer's Pane preferences. This behavior is completely different than the behavior a right-click presents when in the other editors.
Just a little tip!
