Holding shift will allow users to click and select multiple lines.
The behavior is similar to GitHub.
Complete with tests.

Background:
Given I sign in as a user
And I own project "Shop"
And I visit project source page
And I click on "Gemfile.lock" file in repo
@javascript
Scenario: I click line 1 in file
When I click line 1 in file
Then I should see "L1" as URI fragment
And I should see line 1 highlighted
@javascript
Scenario: I shift-click line 1 in file
When I shift-click line 1 in file
Then I should see "L1" as URI fragment
And I should see line 1 highlighted
@javascript
Scenario: I click line 1 then click line 2 in file
When I click line 1 in file
Then I should see "L1" as URI fragment
And I should see line 1 highlighted
Then I click line 2 in file
Then I should see "L2" as URI fragment
And I should see line 2 highlighted
@javascript
Scenario: I click various line numbers to test multiselect
Then I click line 1 in file
Then I should see "L1" as URI fragment
And I should see line 1 highlighted
Then I shift-click line 2 in file
Then I should see "L1-2" as URI fragment
And I should see lines 1-2 highlighted
Then I shift-click line 3 in file
Then I should see "L1-3" as URI fragment
And I should see lines 1-3 highlighted
Then I click line 3 in file
Then I should see "L3" as URI fragment
And I should see line 3 highlighted
Then I shift-click line 1 in file
Then I should see "L1-3" as URI fragment
And I should see lines 1-3 highlighted
Then I shift-click line 5 in file
Then I should see "L1-5" as URI fragment
And I should see lines 1-5 highlighted
Then I shift-click line 4 in file
Then I should see "L1-4" as URI fragment
And I should see lines 1-4 highlighted
Then I click line 5 in file
Then I should see "L5" as URI fragment
And I should see line 5 highlighted
Then I shift-click line 3 in file
Then I should see "L3-5" as URI fragment
And I should see lines 3-5 highlighted
Then I shift-click line 1 in file
Then I should see "L1-3" as URI fragment
And I should see lines 1-3 highlighted
Then I shift-click line 1 in file
Then I should see "L1" as URI fragment
And I should see line 1 highlighted
@javascript
Scenario: I multiselect lines 1-5 and then go back and forward in history
When I click line 1 in file
And I shift-click line 3 in file
And I shift-click line 2 in file
And I shift-click line 5 in file
Then I should see "L1-5" as URI fragment
And I should see lines 1-5 highlighted
Then I go back in history

And I should see line 1 highlighted
Then I go forward in history
And I go forward in history
And I go forward in history
Then I should see "L1-5" as URI fragment
And I should see lines 1-5 highlighted
