Hi,
I think that in the next version of Xform, instead of Multiple Browser
and Hold Browser, we could have only on type of Browser, where selection
of several lines could be done by using the Shift key while selecting
the lines. It seems
to be a quite standard way on many machines. And it would simplify the
multiple selection in a browser.
Am I right?
