Tabs and Windows

Function	Shortcut
New Tab	`⌘` + `T`
Close Tab or Window	`⌘` + `W` (same as many mac apps)
Go to Tab	`⌘` + `Number Key` (ie: `⌘2` is 2nd tab)
Go to Split Pane by Direction	`⌘` + `Option` + `Arrow Key`
Cycle iTerm Windows	`⌘` + `backtick` (true of all mac apps and works with desktops/mission control)

In response to this reddit post about failing to understand the Pipes library after a couple of hours. I wanted to show how an experienced haskeller does it, but I'm afraid it also took me quite a few hours, which is why the following list of steps goes on and on.

After all those hours, my opinion is that Pipes is not at all an easy library. I don't know if Conduit is any easier, but otherwise I side with your friend in advising to use something else (perhaps ordinary lazy IO?) instead of Pipes.

Anyway, here is the full brain dump of my steps as I tried to get your three snippets to fit together.

Since you say that you have a hard time combining the snippets, I assume that they must have complicated types. So my first goal is to figure out the type of your first snippet.
hoogle for parseUrl, withManager, etc. No results.
Google for haskell runEffect, find that it's a method from Pipes.Core,
