Hey everyone - this is not just a one off thing, there are likely to be many other modules in your dependency trees that are now a burden to their authors. I didn't create this code for altruistic motivations, I created it for fun. I was learning, and learning is fun. I gave it away because it was easy to do so, and because sharing helps learning too. I think most of the small modules on npm were created for reasons like this. However, that was a long time ago. I've since moved on from this module and moved on from that thing too and in the process of moving on from that as well. I've written way better modules than this, the internet just hasn't fully caught up.

otherwise why would he hand over a popular package to a stranger?

If it's not fun anymore, you get literally nothing from maintaining a popular package.

Mapping Caps Lock to simultaneous Esc and Super (Mod4)

The CAPS key can be mapped to an escape key when pressed once, and a super (mod4) key when used in combination with other keys.

Create the file /usr/share/X11/xkb/symbols/custom_opts with the following:

// Make Caps an additional Escape
hidden partial modifier_keys
xkb_symbols "super_esc" {

key { [ Escape ] };

Hyperlinks (a.k.a. HTML-like anchors) in terminal emulators

Most of the terminal emulators auto-detect when a URL appears onscreen and allow to conveniently open them (e.g. via Ctrl+click or Cmd+click, or the right click menu).

It was, however, not possible until now for arbitrary text to point to URLs, just as on webpages.

In spring 2017, GNOME Terminal and iTerm2 have changed this.

GNOME Terminal is based on the VTE widget, and almost all of this work went to VTE. As such, we expect other VTE-based terminal emulators to catch up and add support really soon. Other terminal emulators are also welcome and encouraged to join!
