Remove Google Keyboard Suggestions With a Simple Gesture
Android: Google’s smart keyboard goes above and beyond to learn to type, but sometimes it gets it wrong. In the latest version, you can now easily delete words from the custom dictionary with a simple long press and drag.
This new feature has been built into Google Keyboard 5.0 along with several other larger features such as one-handed operation and gesture typing enhancements. If you want to delete a sentence while typing, just press and hold the word and drag it up. The trash can icon appears. Let go of the word on the bank and it will disappear forever.
