PowerGREP sports a full-featured built-in file editor for editing both text files and binary files. PowerGREP's editor is built on the same technology as EditPad, a popular text editor designed by Jan Goyvaerts and sold under the JGsoft brand name, just like PowerGREP.

The key advantage of PowerGREP's built-in editor is that it highlights search matches with you preview or execute an action (but not when you use Quick Execute). If you've previewed a search-and-replace action, you can replace individual matches in the editor with just one click. If you executed the search-and-replace, you can revert individual replacements to the original text with just one click. Replacing and reverting individual matches is much more comfortable than answering yes/no for each replacement while the action is executed, as most other grep tools do. The editor supports unlimited undo and redo, so mistakes are easy to fix. The highlighting is automatically updated to reflect replaced matches and reverted replacements.

Mouse Actions

Dragging means to move the mouse before releasing the mouse button you pressed. If you move the mouse pointer to the edge of the editor space while dragging, the text will start to scroll automatically. Modifier keys like shift or control must be pressed before pressing the mouse button and kept depressed until the mouse button is released.

Left click	Moves the text cursor to the spot where you clicked.
Shift+Left click	Moves the text cursor and expands or shrinks the selection. If there is no selection, the text between the old and new cursor positions becomes selected. If you click outside of the selection, the selection plus the text between the selection and the new cursor position becomes selected. If you click inside the selection, the new selection is the text between the original start of the selection and the new cursor position.
Left click+drag	When clicking outside the selection, a new selection is created from the point where you press the mouse button until the point where you release it. When clicking inside the selection, the selected text deleted and inserted again at the spot (outside the selection) where you release the mouse button.
Shift+Left click+drag	Expands or shrinks the selection like Shift+Left click, but then the text cursor is moved and the selection adjusted until you release the mouse button.

If you press Alt while changing the selection with the mouse, and word wrap is off, the selection becomes rectangular.
