| 6829 :san[dbox] {cmd} Execute {cmd} in the sandbox. Useful to evaluate an | 6830 :san[dbox] {cmd} Execute {cmd} in the sandbox. Useful to evaluate an |
| 6830 option that may have been set from a modeline, e.g. | 6831 option that may have been set from a modeline, e.g. |
| 6831 'foldexpr'. | 6832 'foldexpr'. |
| 6832 | 6833 |
| 6834 *sandbox-option* | |
| 6835 A few options contain an expression. When this expression is evaluated it may | |
| 6836 have to be done in the sandbox to avoid trouble. But the sandbox is | |
| 6837 restrictive, thus this only happens when the option was set from an insecure | |
| 6838 location. Insecure in this context are: | |
| 6839 - sourcing a .vimrc or .exrc in the current directlry | |
| 6840 - while executing in the sandbox | |
| 6841 - value coming from a modeline | |
| 6842 | |
| 6843 Note that when in the sandbox and saving an option value and restoring it, the | |
| 6844 option will still be marked as it was set in the sandbox. | |

| 6847 12. Textlock *textlock* | |
| 6848 | |
| 6849 In a few situations it is not allowed to change the text in the buffer, jump | |
| 6850 to another window and some other things that might confuse or break what Vim | |
| 6851 is currently doing. This mostly applies to things that happen when Vim is | |
| 6852 actually doing something else. For example, evaluating the 'balloonexpr' may | |
| 6853 happen any moment the mouse cursor is resting at some position. | |
| 6854 | |
| 6855 This is not allowed when the textlock is active: | |
| 6856 - changing the buffer text | |
| 6857 - jumping to another buffer or window | |
| 6858 - editing another file | |
| 6859 - closing a window or quitting Vim | |
| 6860 - etc. | |
