I don't know if this is mentioned in the help.



According to :help mode-switching, it is not possible to enter visual 
mode

from Ex or command-line mode. Either the table under :help i_esc needs
to be updated or this needs to be fixed.

According to that table, you can enter visual mode only from either 
normal or

select modes.

The following is possible:
   Q
enter Ex mode
   normal v
   normal eee
extend visual area
   visual
quit Ex mode, enter Visual mode

Hmm, seems the table needs an update.
Unfortunately, :visual is ambigious.

Defining new visual-mode motions?

[Joseph Barker]

Hello, all.

I was recently helping someone out with a vim script (camelcasemotion.vim) 
which adds additional motion commands (they treat camel-cased words 
(WordsLikeThis) as separate words, rather than as a single word). This is 
easy enough to do in normal and operator-pending mode. It seems to be very 
complicated to do this in visual mode, though -- calling a function (or 
anything that lets you move the cursor) seems to force you to leave visual 
mode (i.e., doing `vmap ,w :C-Ucall MoveCursor()` will move the cursor to 
the right place, but you're no longer in visual mode).

My approach to this was to call the movement function, set a mark, select 
the previous visual block (with gv) and then jump to the mark that was 
previously set. The mapping that I created to deal with this is the 
following:

vmap silent ,w @=\33:\25call 
SIDCamelCaseMotion('w',1,'v')CRCRm`gvg``

This seems somewhat inelegant, and also clobbers a mark to be able to 
accomplish its magic. Is there an easier way to accomplish the same thing? 
It seems like there should be, but I was unable to figure one out.

Thanks for your help.
