Hack 20. Navigate Your Source Code
Visual Studio lets you go way beyond moving
around with the arrow, Page Up, and Page Down keys. Learn some
keyboard tricks that let you move around in different
ways.
Visual Studio provides a
number of ways to navigate through your source code. This hack will
cover how to use a number of helpful shortcuts as well as how to use
bookmarks to quickly move around in your code.
3.6.1. Navigation Shortcuts
The normal method of moving around in your
source code with the mouse is perfectly acceptable, but it is also
slow. When you are busy typing, it takes time to reach for the mouse,
orient the cursor, and then move to another section of code by
clicking on a line. Visual Studio contains a number of navigational
shortcuts that can keep your hands on the keyboard and help you write
code faster.
3.6.1.1 Navigation history
The first two commands that you can use to navigate are the
View.NavigateBackward (Ctrl and
-)
and
View. NavigateForward (Ctrl-Shift
and -) commands. These keystrokes can best be described as undo and
redo commands, but instead of undoing or redoing actions, these
keystrokes undo and redo navigation. For instance, if you are working
in one method, then use the mouse to move over to another method, you
can jump back to the previous method using the NavigateBackward
keystroke. After changing something in that method, you could then
jump forward again using the NavigationForward keystroke. These
shortcuts also work fine across files and projects. If you are
working in one file and switch to another, you can quickly jump back
using the NavigateBackward shortcut keystroke.
3.6.1.2 Mouseless scrolling
Usually
when you want to scroll, you end up
reaching for the mouse. The nice thing about scrolling is that it
does not move the cursor, whereas using the regular up and down
arrows does move the cursor. Thankfully, Visual Studio includes
commands to scroll the file without moving the cursor. The
Edit.ScrollLineUp and
Edit.ScrollLineDown commands can be accessed by simply
pressing Ctrl while also pressing either the up or down arrow.
3.6.1.3 Go-to brace
Visual Studio includes a number of
commands that will jump to the next occurrence of a code element.
Possibly the most useful is Edit.GoToBrace
(Ctrl-]),
which will jump to the corresponding brace, parenthesis, or bracket
in the document. If the cursor is on a closing brace, it will jump
back to the opening brace; if the cursor is on the opening brace, it
will jump to the closing brace. This keystroke will work only when
the cursor is on a line that includes a brace and only with languages
that use braces (C#, C++, etc.).
3.6.1.4 End and Home
Visual Studio also supports the End and Home
keys through the commands Edit.LineEnd and
Edit.LineStart . Pressing the End or Home key will move
you to the end of the current line or the start of the current line,
respectively. Visual Studio also includes two commands called
Edit.DocumentEnd and
Edit.DocumentStart (Ctrl-End and Ctrl-Home), which will move you to
the end or beginning of the current document.
3.6.2. Bookmarks
Bookmarks
are one of the few computing analogies that make perfect sense.
Bookmarks allow you to mark a place in your code that you want to
come back to, just like a regular bookmark you would use in a paper
book. Creating and using bookmarks is incredibly easy and when used
properly can save time that would otherwise be wasted scrolling and
searching with the mouse.
You can set a bookmark on a specific line in a file using the command
Edit.ToggleBookmark (the
keystroke chord [Hack #24] Ctrl-K,
Ctrl-K). After setting a bookmark, you will see a small blue
indicator next to that line where a breakpoint would normally appear.
You can remove the bookmark by simply using the Edit.ToggleBookmark
command again. You can also quickly move between bookmarks using two
other commands, Edit.NextBookmark (Ctrl-K,
Ctrl-N) and Edit.PreviousBookmark (Ctrl-K,
Ctrl-P) . Using these two commands,
you can quickly jump through all of your bookmarks much faster than
manually searching for that last line you were on using the mouse.
Bookmarks are removed when you close a file, but if you leave files
open and close the solution, they are saved in your user options file
[Hack #4] and will still be
there next time you open the solution. You can also manually clear
all bookmarks by calling the Edit.ClearBookmarks (Ctrl-K,
Ctrl-L) command.
Bookmarks can also be used with the mouse through the Edit
Bookmarks menu.
