Nested reference: Key in to switch levels on/off

How can a level in a nested reference be switched on or off using a keyin.

Solution

In order to be able to switch on/off levels on a nested reference, the following settings/variables need to be checked first, to allow editing and saving the changes to the levels:

Key in:

set refleveloverrides on
(as that is a file specific setting, make it permanent by using
File>Save Settings)

Variables:

MS_LEVEL_EDIT_NESTED_ATTACHMENT_LEVELS = 1
MS_LEVEL_LOAD_ATTACHMENT_FILTERS = 1

To globally switch on/off levels, no matter a view is open or not (you are actually toggling the Global Display option in Level Manager) key in:

General keyin syntax for switching levels in the master file:

level set display on/off "level name"

General keyin syntax for switching levels in all direct attachments (not nested):

level set display on/off file:*.* "level name"

General keyin syntax for switching levels in all nested references attached to direct attachments, so 1st nest depth.

level set display on/off file:

*.*->*.* "level name"

General keyin syntax for switching levels in all nested references, attached to 1st nest depth attachments, so at 2nd nest depth level level set display on/off file:

*.*->*.*->*.* "level name"

As you can see, for each extra nest level, ->*.* is added.
So in short:

Direct attachments use: file:*.*
Nested attachments at 1st nest depth level use: file:*.*->*.*
Nested attachments at 2nd nest depth level use: file:*.*->*.*->*.*
Nested attachments at 3rd nest depth level use: file:*.*->*.*->*.*->*.*
etcetera

The *.* of course can be replaced by the intended filename.extension.
In case the level name contains spaces, it needs to be enclosed in double quotes.

Wildcards ( * ) in the level name can be used too, so a level name like *test* will apply to all the levels that have the word test somewhere in the level name.

To switch on/off nested levels per open view, the same idea applies, key in:

master file syntax:

set levels on/off "level name"

direct attachment syntax:

reference levels on/off "level name" *.*

1st nest depth attachment syntax:

reference levels on/off "level name" *.*->*.*

2nd nest depth attachment syntax:

reference levels on/off "level name" *.*->*.*->*.*

After entering these view specific key-ins, you are prompted to select a view.
The view selection can be added too, using the key in:

selview <(> <<)>view number>.

Example:
In case View #1 is the view to be affected, enter:
set levels on/off "level name";selview 1
reference levels on/off "level name" *.*;selview 1

Note:
the more wildcards, the slower the response will be, so avoid them if
possible and specify intended level and file names.
