Windows will automatically detect the word you’re writing. With the text field focused, write a word on the handwriting panel with your pen. For example, we’ll be using Notepad here, but you can do this in any traditional desktop program or new Windows 10 app. You can input text in any application with a text input field. You’ll need to tap the keyboard button at the bottom of the touch input keyboard to select the default touch keyboard if you want to use it.
Once you switch to the handwriting input panel, it will automatically appear whenever you tap or click the keyboard icon on your taskbar. Touch the title bar of the panel with your stylus or finger to drag it around your screen and position it wherever you want it. To shrink it, tap the “Undock” button to the left of the “x” on the top right corner of the panel. By default, it spans the entire width of your display. Tap the handwriting keyboard icon, which looks like a pen over an empty panel.
