Highlight Usages in File

ReSharper | Find | Highlight Usages in File
Control+Shift+F7
ReSharper_HighlightUsages

The editor automatically highlights usages of a symbol at caret, which is very convenient in short files and for locals in small contexts. However, this kind of highlighting does not always work well in larger contexts because the selection is only there as long as the caret stays at the symbol.

There is also a caret-independent highlighting that stays until you press Esc and applies different configurable colors to read and write access usages. You can toggle this highlighting for a single item or for several different items simultaneously, and then use shortcuts to jump between the highlightings.

Highlight usages in the current document

  1. Do one of the following:

    • To highlight usages of a symbol, set the caret at a declaration or a usage of this symbol.

    • To highlight usages of all types from an imported namespace, set the caret at the using directive (Imports statement in Visual Basic) of this namespace.

    • To highlight usages of specific expression, select this expression.

  2. Press Control+Shift+F7 or choose ReSharper | Find | Highlight Usages in File from the main menu . Alternatively, you can press Control+Shift+A, start typing the command name in the popup, and then choose it there.

  3. ReSharper highlights read usages with blue and write usages with red. The colors are configurable.

  4. The highlights are also duplicated with blue and red markers on the marker bar on the right. Checking these markers may be helpful if not all highlights are visible on the current screen.
    To navigate between the highlighted items, choose ReSharper | Find | Go to Next/Previous Highlight in the menu or press Control+Alt+PageDown / Control+Alt+PageUp. Alternatively, click the status indicator (that should be displaying Themed icon error stripe find next screen gray) in the right top corner of the editor to jump between the highlights.
    When you finish examining the highlights, press Esc to remove them.
