           Summary: TextBox: with AcceptsTab=true, Ctrl+Tab must move to
                    next control
           Product: Mono: Class Libraries
           Version: 2.0
          Platform: Other

Normally Tab moves to the next control on the form.  The TextBoxBase.AcceptsTab
property -- together with Multiline=true -- sets the textbox to use the tab and
insert it into its text.  Then, Ctrl+Tab should be used to replace the normal
Tab behaviour.  In that mode on Mono however Ctrl+Tab is just used to insert a
tab too.

Repro, use e.g. PropGridFormControlTabView.cs.  Set textbox Multiline=true,
observe behaviour in first column.  Set textbox AcceptsTab=true, expect
behaviour in first table second column, but see incorrect behaviour from second
table second column.


Should:
        | Normally       | AcceptsTab & Multiline
---------+----------------+------------------------
Tab      | Cycle controls | Insert tab character
Ctrl+Tab | No effect*     | Cycle controls

Mono:
        | Normally       | AcceptsTab & Multiline
---------+----------------+------------------------
Tab      | Cycle controls | Insert tab character
Ctrl+Tab | No effect*     | !! Insert tab character !!

* -- Or used by other controls, e.g. on TabPanel, its used to cycle through the
tabpages.
