CTRL + M + O will collapse all.

CTRL + M + L will expand all. (in VS 2013 - Toggle All outlining)

CTRL + M + P will expand all and disable outlining.

CTRL + M + M will collapse/expand the current section.

CTRL + M + A will collapse all even in Html files.

These controls are also in the context menu under Outlining.

Right click in editor -> Outlining to find these controls. (After disabling outlining, use same steps to enable outlining.)

For outlining options: Go to Tools -> Options -> Text Editor -> C# -> Advanced -> Outlining for outlining options.

Tools -> Options -> Text Editor -> C# -> Advanced -> Outlining Right-click > Outlining menu

ctrl+m ctrl+o is "collapse to definitions" which doesn't work when editting an xml file. For me ctrl+m ctrl+l expands all and collapses all (as toggle), but not always. I have one file open where it works and one where it only expands all, but not collapse all. Both are xml files. No idea why. – Matthijs Wessels Jan 13 '10 at 13:07

Just to inform (though this is pretty old): ctrl + m + o only collapses all FUNCTIONS, not the classes (or regions etc). ctrl +m + L will toggle expanding, collapsing everything. – paul23 Oct 11 '11 at 11:30
Ctrl + M + M works on selected text too. For instance, in a completely collapsed xml document with your cursor on an element Ctrl + M + M will expand that node but not its children. If you highlight through the closing tag Ctrl + M + M will expand all of that element's children too. – phloopy Nov 15 '11 at 21:57

One specific method when I collapse all stays expanded, anybody know why? – John Demetriou Nov 11 '15 at 10:07
Thx, why this is the first place i saw CTRL+M + M. Just an extra note, Depending on what is highlighted, is what it will open, Function Name - just function - nothing thats collapsed inside of. Highlight all function code - will open and collapse all the highlighted text. – Yogurt The Wise Dec 08 '15 at 21:09

The following key combinations are used to do things:

CTRL + M + M &rightarrow; Collapse / Expand current preset area (e.g. Method)

CTRL + M + H &rightarrow; Collapse / Hide (Expand) current selection

CTRL + M + O &rightarrow; Collapse all(Collapse declaration bodies)

CTRL + M + A &rightarrow; Collapse all

CTRL + M + X &rightarrow; Expand all

CTRL + M + L &rightarrow; Toggle all

There some options in the context menu under Outlining.

CTRL + M + L expands all

CTRL + M + O collapses all

In the MSDN article "Default Keyboard Shortcuts in Visual Studio," see the section "Text Editor" if you're looking for other shortcuts - these 2 are just a few of the many that are available.

As I commented in the top answer, ctl+m+o collapses to definition which doesn't work for xml files. ctl+m+l should toggle it, but for me it sometimes does and sometimes doesn't. – Matthijs Wessels Jan 13 '10 at 13:10
Normal pages the crtl+m+o collapse, the JScript outling is backwards, for mine, crtl+m+o expands, and the crtl+M+l expands. – Yogurt The Wise Aug 31 '12 at 18:27

In Visual Studio 2017, It seems that this behavior is turned off by default. It can be enabled under Tools > Options > Text Editors > C# > Advanced > Outlining > "Collapse #regions when collapsing to definitions"

If you mean shortcut then

CTRL + M + M: This one will collapse the region your cursor is at whether its a method, namespace or whatever for collapsing code blocks, regions and methods. The first will collapse only the block/method or region your cursor is at while the second will collapse the entire region you are at.

None of these worked for me. What I found was, in the editor, search the Keyboard Shortcuts file for editor.foldRecursively. That will give you the latest binding. In my case it was CMD + K, CMD + [.

Visual Studio can help you find the answer to your question in a couple of different ways.

Type Ctrl + Q to access Quick Launch, and then enter "collap". Quick Launch will display something like:^†

Menus (1)
    Edit -> Outlining -> Collapse to Definitions (Ctrl+M, Ctrl+O)
NuGet Packages (1)
    Search Online for NuGet Packages matching 'collap'

From there, enter "outlining" to find other menu entries related to outlining:

Menus (5)
    Edit -> Outlining -> Toggle Outlining Expansion (Ctrl+M, Ctrl+M)
    Edit -> Outlining -> Toggle All Outlining (Ctrl+M, Ctrl+L)
    Edit -> Outlining -> Stop Outlining (Ctrl+M, Ctrl+P)
    Edit -> Outlining -> Stop Hiding Current (Ctrl+M, Ctrl+U)
    Edit -> Outlining -> Collapse to Definitions (Ctrl+M, Ctrl+O)
Options (4)
    Text Editor -> Basic -> VB Specific (Change outline mode, Automatic inser...
    ...

However, note that Quick Launch will show you only those commands that are available as Visual Studio menu entries. To find other keyboard-related commands related to collapsing sections of code, in the Visual Studio menu bar click:

Tools -> Options -> Environment -> Keyboard

This will display the keyboard section in the Options dialog box. In the "Show commands containing" text box, enter "edit.collap". Visual Studio will display a list that is something like:

Edit.CollapseAllincurrentblock    
Edit.CollapseAllOutlining           Ctrl+M, Ctrl+A (Text Editor)
Edit.CollapseBlockcurrentblock
Edit.CollapseCurrentRegion          Ctrl+M, Ctrl+S (Text Editor)
Edit.CollapseTag                    Ctrl+M, Ctrl+T (Text Editor)
Edit.CollapsetoDefinitions          Ctrl+M, Ctrl+O (Text Editor)

You'll need to click each command to see its associated keyboard shortcut.

For Visual Studio 2021 update.

I've been through all the answers but none worked for me for this update.

So posting a simple way to find out the shortcut as this shortcuts vary for different version. Go to Help → Keyboard Shortcut Preferences (Ctrl + K Ctrl + R) It will take you to this pdf which contains all the shortcuts. So search for your desired shortcut that is fold/collapse and use that in your function.

CTRL+Shift+[ → Fold (collapse) region

CTRL+Shift+] → Unfold (uncollapse) region

CTRL+K CTRL+[ → Fold (collapse) all subregions

CTRL+K CTRL+] → Unfold (uncollapse) all subregions

CTRL+K CTRL+0 → Fold (collapse) all regions

CTRL+K CTRL+J → Unfold (uncollapse) all regions

Once you get the shortcut key, You can go to the Keyboard Shortcuts (Ctrl + K Ctrl + S) and search for the shortcut key and replace it with your desired key.

Note: Ctrl + 0 is Control + Zero not Control + Ohh – Agriculturist Dec 01 '21 at 15:52 — Agriculturist, Dec 01 '21 at 15:52

If you want to collapse/expand an area within a class/method (instead of collapsing the entire class/method), you may create custom regions as follow:

 #region AnyNameforCollapsableRegion

 //Code to collapse

 #endregion

This is not at all what regions are for. Regions are for maintainability and readability in code and should be used to group like methods, classes, etc. – Bmize729 Feb 28 '20 at 05:54
