243 | This is a little rarely useful extension that Uploads the selection as |

|
|
245 | not currently secure for use in a multiuser environment as it writes to |
|
|
246 | F</tmp> directly.). |
|
|
247 | |
|
|
248 | It listens to the C<selection-pastebin:remote-pastebin> keyboard command, |

249 | i.e. |

|
251 | URxvt.keysym.C-M-e: perl:selection-pastebin:remote-pastebin |

254 | the textfile. This command can be set via a resource: |
