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 particuliar, if SINGULAR is able to load that library and if the environment variable `SINGULARHIST` is set and has a name of a valid file as value, then the input history is stored across sessions using this file. Otherwise, i.e., if the environment variable `SINGULARHIST` is not set, then the history of the last inputs is only available for previous commands of the current session.
