Have you ever tried to insert a special character such as the cent sign or the copyright symbol, only to realize that this key isn’t available on your normal keyboard? Here’s how you can make an AutoHotkey script that will let you easily insert any character you want. The Problem Special characters can often be annoying to use. There are many different ways to insert special characters, and many programs have specific ways to insert them. For example, in Microsoft Word you can insert a special character from the Symbol button on the Insert tab in the ribbon. Word also has specialized keyboard shortcuts for many of the common special characters. For example, you can insert the Registered Trademark symbol ® by pressing Alt+Ctrl+R.
That’s a rather unwieldy shortcut, but it’s better than the default Windows shortcut for that symbol. If you open the Character Map and select the Registered Trademark symbol, you’ll see that you could enter the ® symbol by pressing Alt+0174.
Now that’s a difficult shortcut to remember. The Solution Thanks to AutoHotkey, we can solve this problem and make our own keyboard shortcuts for our favorite symbols. AutoHotkey is a great tool that we frequently mention here, but if you don’t already have it installed, download it at the link below and setup as normal. Once AutoHotkey is running, you can right-click it’s icon in the tray and select Edit This Script to add your special character shortcut to your script.
