Thanks the CTRL-TAB and SHIFT-CTRL-TAB is now working....

There is a bunch of buffer/windows/tab commands. They all have matching on partial commands (b[uffer] matches b, bu, buf, buff, buffe, buffer)..
and the numbering/ name access of buffers. Buffer 1 might have file.txt and you can access it as ':buf 1' or by ':buffer file.txt'. Not having numbered buffers is fine, just state so, so we know not to use it.
I guess I use the :bn go to next bufffer and :bmod n to get to the nth modified buffer frequently.
I found EX_CMDS in the ex.sh macro file and has this list:
" ! = < > & ABBREVIATE COPY CD DELETE EDIT FILE GLOBAL JOIN K LIST":+\
" MOVE NEXT NUMBER PRINT PUT QUIT QALL READ REWIND SUBSTITUTE":+\
" SET SG SHELL SPLIT T TAG UNDO UNABBREVIATE V VERSION VSPLIT WRITE WQ WQALL WALL X YANK Z BUFDO "
First thing I would do it implement :h[elp] and pop up that list of commands... there is just too many VIM commands... I get frustrated and switch back.
Oh, before doing help command, the partial matching [] of command is important.
Popular [for me

] command your missing:
':vie[w] [++opt] [+cmd] file' use to edit a file in read-only mode.
':fin[d][!] [++opt] [+cmd] {file} Find {file} in 'path' and then |:edit| it.
I'm using ^O to get to the GUI open, but have not figured out a way to do ":find batch.bat" to edit a file in the PATH quickly..
From the VIM help files... guess this post is getting big... should just point you to the help files.
Install VIM 7.2 in default directory...

(argument stuff I don't think is that popular?)
