Flow

Flow is a lightweight and intuitive software solution designed as a shortcut creator, as it enables you to launch programs, open websites, folders or files, simply by pressing a user-defined button on your keyboard.
Despite being an open source utility, Flow requires that you enter a set already-provided of credentials, namely an email address and an activation code, otherwise it will expire in thirty days and you will no longer be able to work with it.
After installing the application, it will display a virtual keyboard enabling you to choose a button and assign it a specific operation. Initially, Flow features several pre-defined actions, such as 'Run Windows Media Player', 'Run Notepad', 'Open www.google.com' and a few others. These however can be removed, so you can fully customize the appearance and function of your keys.
Flow allows you to allot a new function to almost any button on your keyboard, except 'CTRL', 'Caps Lock', 'Enter', 'Alt' Shift', and several more. Aside from that, you can turn any it number, letter, function key or symbol, into shortcuts.
The utility lets you choose a specific item to be opened every time you press a certain key, for instance the letter 'D' for your most used documents, the letter 'F' for your Favorites folder, 'G' for opening the Google homepage, or the letter 'P' to play your favorite game, as well as anything else that satisfies your needs and helps you save time, by quickly performing the action you want. Moreover, you have the option of creating several 'Layouts', that you can switch between. As such, you can have the same key do different things, depending on the 'Layout' you are currently using.
To summarize, Flow is a useful and reliable program designed to provide you with quick access to all the folders, files, applications and websites you use on a regular basis, saving you time and improving your work productivity.
