*sandbox-option*
A few options contain an expression. When this expression is evaluated it may
have to be done in the sandbox to avoid trouble. But the sandbox is
restrictive, thus this only happens when the option was set from an insecure
location. Insecure in this context are:
- sourcing a .vimrc or .exrc in the current directlry
- while executing in the sandbox
- value coming from a modeline
Note that when in the sandbox and saving an option value and restoring it, the
option will still be marked as it was set in the sandbox.
==============================================================================
12. Textlock *textlock*
In a few situations it is not allowed to change the text in the buffer, jump
to another window and some other things that might confuse or break what Vim
is currently doing. This mostly applies to things that happen when Vim is
actually doing something else. For example, evaluating the 'balloonexpr' may
happen any moment the mouse cursor is resting at some position.
This is not allowed when the textlock is active:
- changing the buffer text
- jumping to another buffer or window
- editing another file
- closing a window or quitting Vim
- etc.
