Lynx invokes a built-in Line Editor
|
|
Packit |
f574b8 |
for entering strings in response to prompts, in forms, and for
|
|
Packit |
f574b8 |
email messages if an external editor has not been defined.
|
|
Packit |
f574b8 |
Alternative key bindings are normally available (unless
|
|
Packit |
f574b8 |
Lynx was configured with
|
|
Packit |
f574b8 |
--disable-alt-bindings). If available, they may be
|
|
Packit |
f574b8 |
selected via the “o”ptions menu, or by editing
|
|
Packit |
f574b8 |
lineedit_mode in the “.lynxrc” file.
|
|
Packit |
f574b8 |
|
|
Packit |
f574b8 |
Two such alternative key bindings, which may be available on
|
|
Packit |
f574b8 |
your system, are the

Lynx by opening the special URL

This text cannot be submitted. Normally lines like
|

Packit |
f574b8 |
these would be part of a form that is filled out and
|
|
Packit |
f574b8 |
then submitted. You can move around here and delete

or add text as you like, using the Line-Editor keys.

Packit |
f574b8 |
<samp><dfn>Ctrl-</dfn>key means
|
|
Packit |
f574b8 |
Control+key.
|
|
Packit |
f574b8 |
<dfn>Ctrl-x</dfn> key means first
|
|
Packit |
f574b8 |
Control+x, then key.
|
|
Packit |
f574b8 |
<dfn>M-</dfn>key means Meta+key,
|
|
Packit |
f574b8 |
where Meta is a modifier that can be entered in a variety of
|
|
Packit |
f574b8 |
ways:</samp>
|
|
Packit |
f574b8 |
|
|
Packit |
f574b8 |
|
|
Packit |
f574b8 |
First ESC, then the key. This
|
|
Packit |
f574b8 |
does not work with all systems or on all connections, and if it
|
|
Packit |
f574b8 |
does may not work for some keys (because the ESC character is
|
|
Packit |
f574b8 |
also part of code sequences for "normal" function keys).
|
|
Packit |
f574b8 |
|
|
Packit |
f574b8 |
Alt+key. This works if the
|
|
Packit |
f574b8 |
terminal, console, or comm program is set up to interpret Alt
|
|
Packit |
f574b8 |
as a modifier to send ESC. The Linux console acts like that by
|
|
Packit |
f574b8 |
default for most keys; Kermit can be set up to do it, xterm can
|
|
Packit |
f574b8 |
be for some keys, and so on. But the same caveats as for the
|
|
Packit |
f574b8 |
previous item apply. This Alt mapping may also be possible,
|
|
Packit |
f574b8 |
independent of the ESC character, for some keys in
|
|
Packit |
f574b8 |
Lynx for DOS/i386 or for Win32.
|
|
Packit |
f574b8 |
|
|
Packit |
f574b8 |
Ctrl-x key. Actually, currently
|
|
Packit |
f574b8 |
the same internal table is used for Meta and the Ctrl-x prefix.
|
|
Packit |
f574b8 |
Therefore all M-key combinations
|
|
Packit |
f574b8 |
can also be typed as Ctrl-x key,
|
|
Packit |
f574b8 |
and vice versa.

A few key names may be less familiar now than when
|
|
Packit |
f574b8 |
Lynx was first written: Find,
|
|
Packit |
f574b8 |
Select and Remove. The
|
|
Packit |
f574b8 |
"https://invisible-island.net/xterm/xterm.faq.html#xterm_keypad">XTerm
|
|
Packit |
f574b8 |
FAQ shows some typical keypad layouts of emulators for VT220
|
|
Packit |
f574b8 |
and other DEC terminals.
|
|
Packit |
f574b8 |
|
|
Packit |
f574b8 |
The VT220 did not have a “backspace” key but
|
|
Packit |
f574b8 |
Lynx's default bindings mention it. Both ASCII
|
|
Packit |
f574b8 |
<samp>BS</samp> (backspace) and <samp>DEL</samp> are bound by
|
|
Packit |
f574b8 |
default to the same functions. <samp>DEL</samp> (occasionally
|
|
Packit |
f574b8 |
referred to as <samp>RUBOUT</samp>) is not the same as
|
|
Packit |
f574b8 |
<samp>Delete</samp>: the former is a single character while the
|
|
Packit |
f574b8 |
latter is usually a sequence of characters.
|
|
Packit |
f574b8 |
|
|
Packit |

|
|
Packit |
f574b8 |
|
|
Packit |
f574b8 |
|
|
Packit |
f574b8 |
"next" means the character "under" a box or
|
|
Packit |
f574b8 |
underline style cursor; it means "to the immediate right of" an
|
|
Packit |
f574b8 |
I-beam (between characters) type cursor.
|
|
Packit |
f574b8 |
|
|
Packit |
f574b8 |
Follow Ctrl-V with any recognized key command,
|
|
Packit |
f574b8 |
to "escape" from a text input field.
