EUREKA:
I found in Xojo 15r1 Release Notes (while searching something else) this important entry 13259:
Alt-Shift-Click
in an IDE item will copy its name into the cursor location (my interpretation of the Feature).
This is a feature that existed in the original REALbasic (v1) application, was lost in version 2005 (or so), was once more lost (in Xojo ?) and at last was back a year ago !
This entry is in the Bug Fixes list.
Although the bug mentioned seems to be back in 2015r4?
It inserts, but when i have text selected (as in the bug report), xojo appends instead of replaces.
Which was the bug?
As far as I understand, it was not a bug per se: we loose the functionality and it was reintroduced.
Im making this kind of error nearly every day(s): so not a bug at all.
I even close a tab or a window in Firefox here and then (cmd-shift-Tab reopen the tab
).
The good part are the increased speed and the lack of typing error(s).
There are many weird things in the IDE to correct
