How to edit a web page IN-PLACE?

[Frank]

Assume I load a webpage into Chrome/Chromium.

Now I want to delete a certain paragraph.

Therefore I don't want to start WebDeveloper pane.

Instead I want to toggle to something like an "edit" mode (via Addon?),

then mark the paragraph and press the DEL key.

I have seen that in the past but cannot remember exactly how it works.

Is an AddOn necessary or is this feature built-in?

You need an extension for that, it is not built into the browser.

"Edit mode" is a built-in feature in all browsers.

You can enable it by typing this in the address bar:

javascript:void(document.designMode='on')

You can add a button that enables this by creating what's called a bookmarklet. i.e. a bookmark whose URL is javascript code.

When you click this bookmarklet in your bookmarks bar, design mode will be enabled or disabled depending on the current state.

javascript:void(document.designMode=document.designMode=='on'?'off':'on')

Ok, thank you. It works - but only partially.

First of all: How do I see if Design Mode is currently ON or OFF?

Of cause without trial and error?

Furthermore your method has a heavy disadvantage:

When I switch back from Design Mode to "Normal" mode the red underlines in web page text do not vanish.

How do I tell Chrome to NOT show these red lines in non-design mode any more?

First of all: How do I see if Design Mode is currently ON or OFF?

Change the bookmarklet to this:

javascript:alert(document.designMode=document.designMode=='on'?'off':'on') 

You''ll see an alert message with the new state of the design mode.

When I switch back from Design Mode to "Normal" mode the red underlines in web page text do not vanish.

This is an ancient bug that's been there since spellcheck exists in Chrome.

I went ahead and reported it just now.

Ok, thank you.

You filed a bug that spellcheck is not AUTOMATICALLY disabled.

But is there (as a workaround) a way to manually (in a second step) disable spellchecking?

[hrg...@gmail.com]

Spellcheck must not be disabled automatically when design mode is turned off. These two properties are independent from each other.

The bug is that the spellcheck red underlines are visible even when the text is not editable. This should not happen.

You can force those red underlines to disappear by disabling spellcheck in the entire page:

document.body.spellcheck = false

But this will also affect text fields such as <input type=text> and <textarea>. This is not what you want.

And this may also not work if one or more child elements set spellcheck=true, because the spellcheck  property is inheritable.

1. Open DevTools(F12) is a simple way, but that's not what you want.

2. In devtools console or a bookmarklet, execute document.designMode='on' is another simple way as hrg.wea said. document.body.spellcheck=false; can disabled spell check globally if elements don't set it.

3. Use an extension, like VisBug. You can select(inspect) an element like a paragraph, then delete it. You can also edit text directly, I found it also has the spell check issue because it's chrome built-in, but when clicking the "search" button of VisBut, the spell check tip can disappear in my test.
