Repeating a Single Command
You may give any
Epsilon command a numeric argument. Numeric arguments can go up to
several hundred million, and can have either a positive or negative
sign. Epsilon commands, unless stated otherwise in their
description, use a numeric argument as a repetition count if this
makes sense. For instance, forward-word goes forward 10
words if given a numeric argument of 10, or goes backward 3 words if
given a numeric argument of -3 .
The argument command, normally bound to Ctrl-U, specifies a
numeric argument. After typing Ctrl-U, type a sequence of digits and
then the command to which to apply the numeric argument. Typing a
minus sign changes the sign of the numeric argument.
You may also use the Alt versions of the digit keys (Alt-1, etc.)
with this command. Note that by default the numeric keypad keys plus
Alt do not give Alt digits. They produce keys like Alt-<PgUp> or
let you enter special characters by their numeric code.
You can enter a numeric argument by holding down the Alt key and
typing the number on the main keyboard. Alt-<Minus> will change
the sign of a numeric argument, or start one at -4 .
If you omit the digits, and just say Ctrl-U Ctrl-F, for instance,
Epsilon will provide a default numeric argument of 4 and move forward
four characters. Typing another Ctrl-U after invoking
argument multiplies the current numeric argument by four, so
typing Ctrl-U Ctrl-U Ctrl-N will move down sixteen lines. In general
typing a sequence of n Ctrl-U's will produce a numeric argument of
4 to the n'th power.
