2022.11.15 - GNU nano 7.0 "Una existencia simple bajo el sol"
• String binds may contain bindable function names between braces.
For example, to move the current line down to after the next one:
bind ^D "{cut}{down}{paste}{up}" main. Of course, braced function
names may be mixed with literal text. If an existing string bind
contains a literal {, replace it with {{}.
• Unicode codes can be entered (via M-V) without leading zeroes,
by finishing short codes with <Space> or <Enter>.
• Word completion (^]) looks for candidates in all open buffers.
• No regular expression matches the final empty line any more.
GNU nano is a simple and easy-to-use editor for on the terminal.
