# Footnotes

### (1)

‘`.info`’, ‘`-info`’, ‘`/index`’, and ‘`.inf`’.

### (2)

The MS-DOS version allows for the Info extension, such as `.inf`, and the short compressed file extensions, such as ‘`.z`’ and ‘`.gz`’, to be merged into a single extension, since DOS doesn’t allow more than a single dot in the basename of a file. Thus, on MS-DOS, if Info looks for ‘`bison`’, file names like ‘`bison.igz`’ and ‘`bison.inz`’ will be found and decompressed by `gunzip`.

### (3)

Of course, you can specify both the file and node in a `--node` command; but don’t forget to escape the open and close parentheses and whitespace from the shell as in: `info --node "(emacs)Buffers"`.

### (4)

Here’s a short summary. `C-x` means press the `CTRL` key and the key x. `M-x` means press the `META` key and the key x. On many terminals th `META` key is known as the `ALT` key. `SPC` is the space bar. The other keys are usually called by the names imprinted on them.

### (5)

`M-x` is also a command; it invokes `execute-extended-command`. See (emacs)M-x section ‘Executing an extended command’ in the GNU Emacs Manual, for more detailed information.

### (6)

Some people are used to calling these operations cut and paste, respectively.

### (7)

Due to the limitations of DOS filesystems, the MS-DOS version of Info looks for a file ‘`_info`’ instead. If the `HOME` variable is not defined, Info additionally looks in the current directory.

### (8)

This file is named ‘`_infokey`’ in the MS-DOS version, and is looked for in the current directory if `HOME` is undefined.
