jed’s help functions are bound to Ctrl-H by default. For example,
Ctrl-H C will show what function a key carries out,
Ctrl-H i will run jed’s info reader, Ctrl-H f will give
help on a particular S-Lang function, etc. However, some modes may use
the Ctrl-H key for something else. For example, if EDT mode is in
effect, then Ctrl-H may be bound to bol which causes the
cursor to move to the beginning of the line. See the section on EDT for
more information.
If jed is properly installed, this entire document is accessable from
within the editor using jed’s info reader. Ctrl-H i will load
info_mode allowing the user to browse the document as well as other
“info” documents.
