What does the following arrow icon mean in the Visual Studio 2012 gutter window? I've never seen it before.
This particular line of code has nothing special about it, nor do I recall doing anything to this line that would cause an arrow to appear. It's definately attached to this line of code. Moving the line of code down causes the arrow to follow.
I have no add-ons installed in Visual Studio.
To unflag a thread, hover over the thread marker in the source code and select the red flag icon to clear it, or right-click the thread marker and select Unflag. In the Threads window, flagged threads have red flag icons next to them, while unflagged threads, if shown, have empty icons.
Find the variable in the Locals window ( Debug > Windows > Locals ), right-click the variable, and select Make Object ID. You should see a $ plus a number in the Locals window. This variable is the object ID. Right-click the object ID variable and choose Add Watch.
Examine thread markers. In the source code, locate the Console.WriteLine(); line. Right-click in the Threads window, and select Show Threads in Source from the menu. The gutter next to the source code line now displays a thread marker icon .
Set a breakpoint on the Console.WriteLine (); line by clicking in the left gutter, or selecting the line and pressing F9. The breakpoint appears as a red circle in the left gutter next to the code line. Select Debug > Start Debugging, or press F5. The app starts in debug mode, and pauses at the breakpoint.
It marks a Task List shortcut. You add them with Edit > Bookmarks > Add Task List Shortcut, [Ctrl+E,T] keystroke. That adds an entry to the task list, use View > Task List to display it. Select "Shortcuts" in the combobox. You'll see a list of all the shortcuts you added. Double-click an entry to jump to the line.
Remove it again with Edit > Bookmarks > Remove Task List Shortcut, [Ctrl+E,T] again.
NOTE: In visual studio 2015 and above, its [Ctrl+K,Ctrl+H]
