+# Use keyboard shortcuts to select URLs.
+# This should be used as a replacement for the default matcher extension,
+# it also makes URLs clickable with the middle mouse button.
+
+# Usage: put the following lines in your .Xdefaults/.Xresources:
+# URxvt.perl-ext-common: ...,url-select
+# URxvt.keysym.M-u: perl:url-select:select_next
+
+# Use Meta-u to activate URL selection mode, then use the following keys:
+# j/k: Select next downward/upward URL (also with arrow keys)
+# g/G: Select first/last URL (also with home/end key)
+# o/Return: Open selected URL in browser, Return: deactivate afterwards
+# y: Copy (yank) selected URL and deactivate selection mode
+# q/Escape: Deactivate URL selection mode
+
+# Options:
+# URxvt.url-select.autocopy: If true, selected URLs are copied to PRIMARY
+# URvxt.url-select.button: Mouse button to click-open URLs (default: 2)
+# URxvt.url-select.launcher: Browser/command to open selected URL with
+# URxvt.url-select.underline: If set to true, all URLs get underlined
