^ Its Ctrl+Shift+L not Ctrl+Alt+L
Couple of tips:
1.Thumbnails in Ctrl+Tab switcher :
Enable
opera:config#UserPrefs|UseThumbnailsinWindowCycle
Now the Ctrl+tab switcher will have thumbnails of the tab along with name.
Good for keyboard freaks like me
2. Inline search.
You can use '/' anywhere in the page , to popup a search bubble.
Also , to get the firefox style search bar ,
Right-Click on the status bar > Customize > Buttons > Search
Add 'Find In Page' to the status bar.
Enable
opera:config#UserPrefs|UseIntegratedSearch
Next time you press Ctrl+F , the search bar you added is given focus automatically instead of popping up an old school style search window.
And pressing 'enter' will take you to the next result.
P.S : Maybe we should have an Opera tips thread?
