AutoHotKey: if you're on windows like me (and starting to feel in the minority on here), this is a must. I've been evangelising AHK for the last 7 years at least, to anyone who will listen. It has saved me days of my life in accumulated time. Here are a few samples of things from my main script which I use daily<p><pre><code> CTRL+@ - paste my email address. saves buckets of time logging into things, signing up to things etc
]t - paste date-time in the format 2016-08-12 09:53
]d - paste date in the format Friday, August 12, 2016
#ho - open windows hosts file in notepad
ALT+MOUSEWHEEL - page up, down with each movement
F11 - switch to thumbnail view in explorer
SHIFT-F11 - switch to detail view in explorer
</code></pre>
I also have a universal autocorrect script which I've filled with common typos so I can't type 'pulbic', 'widnows', 'anywya' etc (had to disable the script to type those in here)<p>On top of this, an autocomplete / intellisense script for html / js dev.<p>Chocolatey: Apt-get for windows. If you ever need to install anything, you can open a web-browser, google the thing you want, open the page, find the installer, download it, open explorer, find the exe, run it, step through the options and get on with your day. OR, if you have Chocolatey installed you can just open powershell and type "choco install vlc" or whatever it is, silently.<p>The best feature of choco is that you can chain things together. You can write a script that installs everything you need in life, and have a new machine up and running in no-time.<p>Synergy+: If you use more than one machine, you can share the mouse, keyboard and clipboard - even across operating systems. Put the two screens side by side, configure, and they might aswell be one machine with two monitors.
