II. What to Know or Do After Installation

KeyScrambler doesn't require you to do anything after you install it on your computer. But in case you wish to tweak the program a little, here are the major components of the user interface, where you can change KeyScrambler's default settings:

Overlay Window

The Overlay Window allows you to:

  1. Bring up the Options Dialog .
  2. Move the Overlay Window Around.

KeyScrambler comes in 3 editions: Personal (free), Professional and Premium (must purchase). The Overlay indicates which KeyScrambler edition you've installed.

 

When you begin typing in a protected app, a small rectangular green Overlay Window will appear on the center top of your computer screen displaying the ongoing encryption. When you stop typing, the Overlay Window will fade away in 4 seconds.

Tray Icon

The Tray Icon allows you to:

  1. Know KeyScrambler's operating status by its color.
  2. Turn KeyScrambler on/off.
  3. Bring up Mini Menu.

** Make Tray Icon visible »

Note: If you are using Windows 7 or 8, at times you may find your KeyScrambler Tray Icon missing. Click the link above.

The KeyScrambler Icon is located in the Tray Area at the bottom right of your computer screen.

  1. The Tray Icon's color is green when KeyScrambler is active, red when it's turned off, and yellow when it's inactive, because the app in use is not supported by the KeyScrambler Edition you're using.
  2. Double-clicking the Tray Icon turns KeyScrambler on/off.
  3. Right-clicking the Tray Icon brings up the Mini Menu, a convenient way to access the Options dialog boxes.

Options

You can do the following in Options:

  1. General: Reset Product Key.
  2. Dispaly: Hide Overlay Window.
  3. Advanced: Disable Support for East Asian Languages.
  4. Anti-Profiling: Change the strength of Anti-Keystroke-Profiling.

1. The General dialog box.

Here you find the Off/On hot key for KeyScrambler. You can also reset your Product Key here.

 

2. The Display dialog box.

The default setting selects Both to display the Overlay Window and the Tray Icon. You can choose to hide the Overlay Window or Tray Icon from your screen.

To hide the Overlay Window from view, select only Tray Icon and click OK. The deselected Overlay Window disappears from your computer screen.

Note: It's important to keep the Tray Icon visible on your screen at all times. It keeps you informed of KeyScrambler's operating status besides other functions.

3. The Advanced dialog box.

The default setting selects Support East Asian Language Input (Pro or Premium) to protect your keyboard entries in Chinese, Japanese, and/or Korean. If you don't need this feature, deselect it and click OK.

Note: This option is not compatible with HP notebooks that have the QuickPlay software installed. You should either keep this option unselected or uninstall QuickPlay.

4. Anti-keystroke-Profiling dialog box.

The anti-profiling feature is unselected by default.

If you choose to enable the feature, you'll notice that the strength for Anti-Keystroke-Profiling is set at 3, a point at which a balance is achieved between the effective alteration of your natural keystroke flow against keystroke profiling and the extent to which the alteration is visible to you.

If you wish for stronger protection against keystroke profiling, you can move the blue indicator to the right.

Note: Strength greater than 3 will result in a more than average amount of variations--longer pauses and more frequent jumps--in your keystroke flow, hence a more distorted typing pattern for keystroke profiling websites.

 

Options consists of six tabs: General, Display, Update, Advanced, Anti-Profiling, and About.

Clicking any of the tabs will open up the respective dialog boxes. This is where you can change some of KeyScrambler's default settings and check if you have the latest update.

Clicking Options opens the General dialog box.
