This one is for iPhone users. All of us know that it can be difficult to land the cursor exactly where you want it, using a finger. Sometimes a whole word gets selected, sometimes it lands a letter away making it tedious to move it a step to the left or right.
Well, Apple did implement a little known solution in iPhone: a long press of the spacebar makes the entire keyboard a mini trackpad. Learning this made my life much easier as I do a lot of typing on my phone. If your phone supports 3D touch, you can press down hard anywhere on the keyboard to activate this, and press again to activate selection. Neat.
