Block folding
terraform-mode sets up outline-mode variables for block folding.
To use outline-mode for block folding, enable outline-minor-mode
in terraform-mode-hook:
(add-hook 'terraform-mode-hook #'outline-minor-mode)You can use outline-toggle-children bound to C-c C-f to toggle
visibility of a block at point.
We also provide function terraform-toggle-or-indent which
folds-or-indents. It is not bound by default, but you can bind it to
TAB or any other key.
Access to Terraform resource documentation
Within a resource or a data block, type C-c C-d C-w to open a new
browser tab with the resource or data documentation page.
Type C-c C-d C-c to kill the URL (i.e. copy it to the clipboard) for the documentation page rather than directly open it in the browser.
You can also type C-c C-d C-r to insert a comment containing a link to
this documentation right above the resource or data block.
Customize Variables
terraform-indent-level(Default: 2)
Indentation size. You need to call revert-buffer if you change this value outer of hook such as eval-expression.
terraform-format-on-save(Default nil)
Set to t to automatically format the buffer on save.

This major-mode inherits from hcl-mode. Most of syntax features, like highlighting, indentation are implemented in hcl-mode.
