Thanks Rodney,
Your example on how to order things was what I needed. The sequence you put in your example is what the current version of SlickEdit does, but it is not what I expect.
After analysing what is happening what I expect is a straight MRU, and this what previous versions of SlickEdit gave me.
Here are some sequences and what I think should happen.
#1 Let's have A, B and C open in that order, A selected.
#2 Ctrl-Tab activates B
#3 Ctrl-Tab activates A, so far so hoopy
#4 Open file D
#5 Ctrl-Tab now now takes you to B, not A.
Next sequence (your example):
#1 Let's have A, B and C open in that order, A selected.
#2 Ctrl-Tab activates B
#3 Ctrl-Tab activates A, so far so hoopy
#4 Ctrl-. activates C
#5 Ctrl-, activates A
#6 Ctrl-Tab activates B, when the most recently used file was C
Next sequence:
#1 Let's have A, B, C and D open in that order, A selected.
#2 Ctrl-Tab activates B
#3 Ctrl-Tab activates A, so far so hoopy
#4 Ctrl-. activates C
#5 Click on D
#6 Ctrl-, activates A
#7 Ctrl-Tab activates B, when the MRU file as D
I can continue....
Regards.
