Select inputs by holding CTRL and clicking on the input field, or by holding CTRL + SHIFT and making a rectangle, in which all inputs get selected. Then whatever you type will be typed to the end of those inputs, or you can press backspace to erase a letter from the back of the input.
Note: this won't work on the currently selected input so you must click outside of the inputs after selecting
