Miscellaneous
You can use the eval command to quickly evaluate an arbitrary
EEL expression, or do simple integer-only math. Similarly, the
execute-eel command executes a line of EEL code that you type
in. Both commands are available in 32-bit Windows versions and under
Unix.
The command narrow-to-region temporarily
restricts your access to the current buffer to the region between the
current values of point and mark. Epsilon hides the portion of the
buffer outside this region. Searches will only operate in the
narrowed region. While running with the buffer narrowed, Epsilon
considers the buffer to start at the beginning of the region, and end
at the end of the region. However, if you use a file-saving command
with the buffer narrowed in this manner, Epsilon will write the
entire file to disk. To restore normal access to the buffer, use the
widen-buffer command.
Under DOS and Windows, you can set Epsilon's
key repeat rate with the key-repeat-rate variable. It
contains the number of repeats to perform in each second. Setting
this variable to 0 lets the keyboard determine the repeat rate, as it
does outside of Epsilon. Epsilon never lets repeated keys pile up;
it ignores automatically repeated keys when necessary.
