JOVE: UNIX Text Editor -- A Basic Helpsheet
Jove is a basic text-processor for the UNIX operating system and can be invoked with the standard [command] [filename] sequence. It appears to have an upper limit with regard to file size, about 2-3meg, and lines within the file can't be more than 1024 characters long. In addition, search-strings can't cross line-ends.
On University of Virignia machines, further help can be obtained by entering "teachjove" at the Unix prompt.
Note: If you experience a system crash or inadvertently exit Jove without saving, you can run it in recovery mode: jove -r [filename]
Jove will look for any Jove buffers owned by you and allow you to recall them.
Convention for the commands list:
Ctrl-[chr] means hold the CONTROL key while typing the character [chr]. Thus, C-F would be: hold the CONTROL key and type F.
Meta-[chr] means type the META (ESCAPE) key and release it, then type the character [chr]. The [chr] can be upper or lower case and it will have the same meaning.
