This dialog box lets you change global settings for the Visual Studio code and text editor. To display this dialog box, select Options on the Tools menu, expand the Text Editor folder, and then select General.
The Settings section of Tools > Options > Text Editor > General includes the following options.
When selected, this setting enables you to move text by selecting and then dragging it with the mouse to another location within the current document or any other open document.
When selected, delimiter characters that separate parameters or item-value pairs, as well as matching braces, are highlighted.
When the code editor is selected, a vertical yellow line appears in the selection margin to mark code that has changed since the file was most recently saved. When you save the changes, the vertical lines become green.
By default, the editor detects encoding by searching for byte order marks or charset tags. If neither is found in the current document, the code editor tries to auto-detect UTF-8 encoding by scanning byte sequences. To disable the auto-detection of encoding, clear this option.
When selected, the project's specified coding conventions override any coding conventions you use on your personal projects.
When selected, you can press Ctrl and hover over an element while clicking the mouse. Doing so takes you to the definition of the selected element. You can also choose either Alt or Ctrl + Alt from the Use modifier key drop-down.
Select this check box to display the element's definition in a window without navigating away from your current location in the code editor. For more information, see How to: View and edit code by using Peek Definition.
The Display section of Tools > Options > Text Editor > General includes the following options.
When selected, displays a vertical margin along the left edge of the editor's text area. You can click this margin to select an entire line of text, or click and drag to select consecutive lines of text.
| Selection Margin on | Selection Margin off |

When selected, displays a vertical margin outside the left edge of the editor's text area. When you click in this margin, an icon and ToolTip that are related to the text appear. For example, breakpoint or task list shortcuts appear in the indicator margin. Indicator Margin information doesn't print.
When selected, displays a gray box around the line of code in which the cursor is located.
When selected, vertical lines appear in the editor that line up with structured code blocks, which lets you easily identify the individual blocks of code.
