Singular Manual: Editing input

| ### 3.1.5 Editing input The following keys can be used for editing the input and retrieving previous input lines: `TAB` provides command line completion for function names and file names `CTRL-B` moves cursor to the left `CTRL-F` moves cursor to the right `CTRL-A` moves cursor to the beginning of the line `CTRL-E` moves cursor to the end of the line `CTRL-D` deletes the character under the cursor Warning: on an empty line, `CTRL-D` is interpreted as the `EOF` character which immediately terminates SINGULAR. `BACKSPACE` `DELETE` `CTRL-H` deletes the character before the cursor `CTRL-K` kills from cursor to the end of the line `CTRL-U` kills from cursor to the beginning of the line `CTRL-N` saves the current line to history and gives the next line `CTRL-P` saves the current line to history and gives the previous line `RETURN` saves the current line to the history and sends it to the SINGULAR parser for interpretation When run under a Unix-like operating system and in its ASCII-terminal user interface, SINGULAR tries to dynamically link at runtime with the GNU Readline library. See section `Command Line Editing' in The GNU Readline Library Manual, for more information. If a shared version of this library can be found on your machine, then additional command-line editing features like history completion are available. In particular, if SINGULAR is able to load that library the input history is stored across sessions using the file given in the environment variable `SINGULARHIST`. If `SINGULARHIST` is not set `.singularhistory` is used. Otherwise, i.e., if the environment variable `SINGULARHIST` is set to the empty string, the history of the last inputs is only available for previous commands of the current session.
