Shortcut: Ctrl+O
Open an existing file from disk. A standard file open dialog window will open to select the file. To select multiple files, hold down the Shift or Control key on the keyboard while you click with the mouse.
If the active file is empty and unsaved, it will be replaced by the newly opened one.
Files opened will be added to the top of the recent file list.
A long click on the button will open the Recent Files menu. Selecting a file from this menu will open it.
