Precisely select text without lifting your fingers—much faster than the magnifying glass method:

1. Long-press the space bar → keyboard turns into a track-pad.
2. Drag to the start of the text.
3. Keep one finger down, tap with a second finger anywhere on the keyboard to enter selection mode.
4. Drag the first finger to the end of what you want highlighted.

This two-finger technique provides pixel-perfect text selection and works in any app that supports text selection, making it invaluable for editing documents, messages, and notes.
