Command to collapse all sections of code?

Question

In Visual Studio is there a command to collapse/expand all the sections of code in a file?

Answer 1

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.

Answer 2

The following key combinations are used to do things:

CTRL + M + M → Collapse / Expand current preset area (e.g. Method)

CTRL + M + H → Collapse / Hide (Expand) current selection

CTRL + M + O → Collapse all(Collapse declaration bodies)

CTRL + M + A → Collapse all

CTRL + M + X → Expand all

CTRL + M + L → Toggle all

There some options in the context menu under Outlining.

Answer 3

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.

Answer 4

CTRL+M expands region.

CTRL+L collapses region.

Answer 5

• Fold/Unfold the current code block – Ctrl+M, Ctrl+M
• Unfold all – Ctrl+M, Ctrl+L
• Stop outlining – Ctrl+M, Ctrl+P
• Fold all – Ctrl+M, Ctrl+O

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"

Answer 7

CTRL + M + A collapses all

works for me, whereas

CTRL + M + O

You can do: Control + M then Control + L to toggle all outlining

Answer 9

In Visual Studio 2013:

Answer 11

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.

if you want to collapse and expand particular loop, if else then install following plugins for visual studio.

• VS2010

• VS2013

Answer 15

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 + [.

Answer 16

Collapse All - Ctrl + M + O

Expand All - Ctrl + M + L

Answer 17

In case of ugrading to Visual Studio 2010, 2012, 2013 or 2015, there's a Visual Studio extension to show current registered keyboard shortcuts, IntelliCommand.

Answer 18

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.

Answer 19

In Visual Studio 2019:

Go to Tools > Options > Keyboard.

Search for Edit.ToggleAllOutlining

Use the shortcut listed there, or assign it the shortcut of choice.

Answer 20

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
