Action Menu for iPhone is quite a handy tweak. It brings the missing feature of clipboard/ pasteboard along with cut copy paste feature available on firmware 3.0/ iPhone 3GS. The tweak works terrifically smoothly and also has a nice loading speed, unlike clippy. It also has an advanced version which is paid which brings features like dial, search history etc to iPhone.
Personally its my favourite tweak by cydia as it brings clipboard tab keeping intact all the other features/ tabs like copy, copy all, cut, correction (inspell) and paste. It also has page scrolling feature/tab included in the free package available for $2.99
To use the tweak you have to go to settings/action menu, where you can edit the settings. You have an option to use icons or names for the tabs under its settings.(I prefer using tabs). To add things to the clipboard you need to add them as favorite and then type anything you want.
The only missing feature is that you can’t directly add things to clipboard, but I expect the developer to put this feature in the coming updates to the app. To download the app search for ‘action menu’ on Cydia. See the screenshots below to see how the tweak works.
