| 142 If you set @code{scroll-step} to a small value because you want to use | |
| 143 arrow keys to scroll the screen without recentering, the redisplay | |
| 144 preemption will likely make XEmacs keep recentering the screen when | |
| 145 scrolling fast, regardless of @code{scroll-step}. To prevent this, set | |
| 146 @code{scroll-conservatively} to a small value, which will have the | |
| 147 result of overriding the redisplay preemption. | |
