You can auto-hide any toolbar in Opera after enabling it via keyboard shortcut or mouse gesture or button.
Keyboard shortcut / Mouse gesture
Create new keyboard shortcuts or mouse gestures in Application section with following action codes.
| Toolbar | Action code for keyboard shortcut or mouse gesture |
|---|---|
| Menu bar | Enable menu bar & Delay, 12000 & Disable menu bar |
| Main bar | View main bar, 6 & Delay, 10000 & View main bar, 0 |
| Personal bar | View personal bar, 6 & Delay, 12000 & View personal bar, 0 |
| Tab bar | View page bar, 6 & Delay, 10000 & View page bar, 0 |
| Address bar | View address bar, 6 & Delay, 10000 & View address bar, 0 |
| Navigation bar | View navigation bar, 6 & Delay, 10000 & View navigation bar, 0 |
| View bar | Set alignment, “Document view toolbar”, 6 & Delay, 8000 & Set alignment, “Document view toolbar”, 0 |
| Status bar | View status bar, 6 & Delay, 12000 & View status bar, 0 |
To modify auto-hide time, change Delay, X value (time in milliseconds) in above code.
To hide/show a toolbar without auto-hide use the following.
| Toolbar | Action code for keyboard shortcut or mouse gesture |
|---|---|
| Menu bar | Enable menu bar | Disable menu bar |
| Main bar | View main bar, 6 | View main bar, 0 |
| Personal bar | View personal bar, 6 | View personal bar, 0 |
| Tab bar | View page bar, 6 | View page bar, 0 |
| Address bar | View address bar, 6 | View address bar, 0 |
| Navigation bar | View navigation bar, 6 | View navigation bar, 0 |
| View bar | Set alignment, “Document view toolbar”, 6 | Set alignment, “Document view toolbar”, 0 |
| Status bar | View status bar, 6 | View status bar, 0 |
Button
You can add buttons to any toolbar (main bar, tab bar, address bar, navigation bar, view bar, status bar, start bar or panels) except menu bar & personal bar simply by dragging button links to required place. Clicking on the button links without dragging will add the buttons to Tools → Appearance → Buttons → My Buttons for later use.
When you try to add a button, a dialog box with following message will popup. Press OK to add button.
Adding new button with action
[Action]
Do you want to proceed?
To remove a button, right-click on it and select Remove From Toolbar.
Get buttons for above from here as Opera button links won’t work in Opera Watch (WordPress).

No way to get the toolbars to appear when hovering over the area, is there?
using
Currently, not possible.

I never realized this but you cannot re-arrange toolbars however you want. When trying to convert my brother to use Opera, he was used to how all the other browsers have the following toolbar stack:
You ~can~ accomplish this in Opera with a mix of completely rebuilding existing toolbar using the customize menu along with turning some toolbars off, but this isn’t exactly an easy way to accomplish the same look’n'feel of all other browsers.
I love how Opera stacks its toolbars, but i can see how non-Opera users would be annoyed by not being able to get it to look like how they are used to very easily.
That is, unless there’s some slick way to accomplish this that I don’t know about.
using
toolbar stack i tried to provide in previous comment:
menu bar
address bar
links/bookmarks bar
tab bar
using
Download Tab bar below address bar.ini, place it inside toolbar folder in your profile and activate Opera Standard (Tab bar below address bar) toolbar setup

> You can auto-hide any toolbar in Opera
Even the Start bar? Are you sure?
You are also missing the instructions for the View and Navigation bars. Can you autohide them?
For example, How do I turn the “eyeglass” button on the Address bar show an autohiding View bar? I really want to know because I always want it disappearing when I’m done picking one of the view options.

Great stuff (at least for me)
Can I do the similar “AUTO HIDE” to the left panel
e.g. in email M2 I want to assign a keybioard shortcut to Show/Hide the mail panel at left.
Thanks!!! edmond
using
It is already available (CTRL+SHIFT+3). If you want to hide panel selector, use Focus panel, “mail” | Set alignment, “hotlist”, 0
using
Great Tamil !!
Thanks to the advise and I’m going to try it with the DELAY option.
using
No Luck to get it work………..
I did this:
Enable Focus panel, “mail” & Delay, 12000 & Disable focus panel, “mail”
Mail panel shows, but did not draw back (HIDE) after 12000 mi sec.
Thanks
using
Use the following.
Focus panel, “mail” & Delay, 12000 & Set alignment, “hotlist”, 0
using
Tamil, Thanks to to your time.
It works, however, just to show up the side panel at left, and does not withdraw back (auto hide) afterwards. I copied your
Focus panel, “mail” & Delay, 12000 & Set alignment, “hotlist”, 0
I asssigned a keyboard short cut, it works just to show the panel at left in the M2 mail interface.
Anyway, Thanks to the time and it is not as of any importance to me,

add………….
As I just want it SHOWS the left panel and AUTO HIDE itself in a short period as I need the panel to choose some of the filters and I am using eeepc so the screen is rather small especially if the left panel is always there.
Thanks again!!!! edmond

Thanks- very useful tips. But what i really want to know is how to remove toolbars and make them stay removed. Opera Help has been helpless on that score [but it's great on how to remove PARTS of toolbars, "buttons"].
A minimalist, i like to hide my main and address bars, but every time i open Opera, it has forgotten my preferences, and redisplays them. Grrr.

Marinus,
If you want to remove toolbars which in my understanding, Please try followings:
Move your mouse cursor to the toolbar which you’d like to remove.
Until your cursor reach there, right click.
Choose customise
Lookup “Placement”
It should be saying top or bottom…etc.
Now, sleect “OFF”.
Hope this is what you want.
Thanks edmond

Took some time to figure out , but works.

Edmond:
Well, half. But i think most clutter-sensitive folks want toolbars hidden till needed, then instantly appear with a hotkey. Your fix does only the first part. Also: your method doesn’t work on main menu bar.
Firefox can do this with aid of “Hide Tab Bar”, “Hide Navigation Bar”, and “Hide MenuBar” extensions. Which is why i’ve switched to Firefox. Unfortunately Opera Inc. is in a state of denial about their wretched widgets system. I predict FireFox will continue to steal market share from them for this reason. Pity- Opera is my sentimental favourite.
Firefox doesn’t have Opera’s lovely it-just-works “Zoom to Fit”, or its just-plain-better scrollbars [don't enlarge with page zoom, and disappear entirely in full-screen mode]. And worst,
with any # of extensions at all, FireFox is unstable! You can’t win!

How come youtube can’t play in all these other browsers other than IE, you get a msg that your flash player is outdated but this doesn’t help.

@Xpatworkiscrazy: Not that it has anything to do with the topic of this post, but IE uses a different form of the Flash player than every other browser on the planet. You can download the version of Flash Player that runs on Opera, Firefox, Safari, Chrome, etc. at http://www.adobe.com.
