Zamienienie textu - Notepad++

You can enable and disable overtyping (that is, instead of inserting characters at the cursor, you replace them) by pressing insert, or clicking on the rightmost section of the statusbar, which will indicate the current mode: INS for inserting characters, OVR for overwriting them (overtype). The ekraned cursor will also change shape accordingly (see also Preferencje for the cursor).
