UltraEdit supports dragging and drop editing using the mouse. Drag and drop editing allows you to select text in the normal manner and then copy or move the selected text by dragging it to a new location with the mouse. No keyboard interaction is required.
Initially you select text in the normal manner. Once text has been selected, you may click the primary mouse button (usually the left button) on the selected text, at which time the mouse pointer changes to a pointer with a small dotted rectangular box at the bottom of the pointer. This pointer indicates you are in the drag and drop editing mode and may drag the selection to a new location.
While keeping the primary mouse button down the selected text may be dragged to a new location. As you move the mouse the cursor will follow the mouse and the cursor indicates the new position of the text if you stop pressing the mouse button (and "drop" the text).
You can even drag the text from one file to another within UltraEdit. If the mouse is positioned over a different file within UltraEdit, that file will become active and the text may be dropped into that file at the cursor position shown.
At any time, pressing Esc will cancel the drag and drop mode.
Additionally, instead of moving the text being dragged, it may be copied to a new location. To do this, hold the Ctrl key while dragging the selection and the mouse pointer will show a small "+" symbol beside it indicating the text will be copied to the new location indicated by the cursor and also remain in the original position.
Drag and Drop editing is supported in normal, hex edit mode, and column mode.
