View source for IS SCH

== Introduction ==

The '''S'''ingle '''CH'''aracter packet is used to send individual key presses to LFS. Standard keys (e.g. V and H) should be sent as capital letters, using the corresponding ASCII values. This does not work with keys such as F keys, arrows, CTRL, etc. For those, you should send an [[IS_MST]] packet with the <code>/press</code>, <code>/shift</code>, <code>/ctrl</code>, or <code>/alt</code> commands.

Note that some keys seem not to work properly with this packet, for instance H does not toggle chat history, and I does not toggle ignition. On the other hand, V does change the view, and 9 does turn the hazard lights on.
