Navigating Up or Down a Page in Vim

Navigating Up or Down a Page in Vim

When you want to have an overview of a file, you can get a good overview just moving down a few pages.

To move a page down in Vim, press the Ctrl + f key combination, and to move a page up, press the Ctrl + b key combination.

  • Ctrl+f: Page down
  • Ctrl+b: Page up

If you want a more granular control, read along!

Moving Page Down

There are several ways you can move the cursor downwards in Vim.

You can move the cursor down one full screen or you can move it down only half the screen.

Page forward one screen

Page down is a common action to perform that moves down one full screen.

To move down one full screen, make sure you are in Normal mode and then press Ctrl + f key combination.

You can remember this thinking that the ‘f’ in “Ctrl + f” stands for forwards.

Alternatively,  you can also press the Page Down key on your keyboard (that is above the arrow keys).

This operation is also called a page forward operation.

Scroll forward half a screen

Sometimes it makes more sense to scroll down just a little bit.

In those cases, you can use the Ctrl + d key combination. Make sure you are in Normal mode before you press this key combination.

If you have trouble remembering this key combination, you can think of the ‘d’ in “Ctrl + d” as downwards.

This operation is also referred as a scroll forward operation.

Moving Page Up

Just like Page Down, there are several ways you can move the cursor in the upwards direction in Vim.

Either you move it one full screen up or move it half a screen up.

Page backwards one screen

Vim allows you to go up a full screen.

To scroll up a full screen, enter Normal mode and press the Ctrl + b key combination.

You can remember this by thinking that the ‘b’ in “Ctrl + b” stands for back[wards].

If present on your keyboard (usually above the arrow keys), you can make use of the Page Up keys to perform the same action as “Ctrl + b”.

This operation is also called a backwards scroll.

Scroll backwards half a screen

You can move half a screen in the upwards direction in Vim.

Scrolling up half a screen can be done by pressing the Ctrl + u key combination. Make sure you are in Normal mode before you press it, though.

If you have any trouble remembering this, think of the ‘u’ in “Ctrl + u” as up[wards].

This operation is referred as a backwards scroll operation.

FTC to Crack Down on Illegal Sharing of Citizen’s data

Posted on by Kernel

The U.S Federal Trade Commission (FTC), the U.S agency primarily responsible for consumer protection, warned that they would be cracking down on companies which illegally share or sell sensitive consumer data.

This warning is in response to a growing consumer awareness surrounding the private market of personal data and the inability of a consumer to reasonably prevent such usage.

“While many consumers may happily offer their location data in exchange for real-time crowd-sourced advice on the fastest route home, they likely think differently about having their thinly-disguised online identity associated with the frequency of their visits to a therapist or cancer doctor,” FTC’s Kristin Cohen said.

Instances of one such practice which may no longer be ignored by the FTC are software development kits (SDKs) embedded in mobile apps. These SDKs gather personal data that is supposedly anonymous and then sell the aggregates.

This practice, at its core, collects the personal data of a knowing or unknowing consumer and turns it into a profit. The consumer sees none of these benefits.

Furthermore, as the FTC notes, the abuse of mobile location and health information exposes users to significant harm.

“These companies often build profiles about consumers and draw inferences about them based on the places they have visited.”

The crack down consists of enforcing, what the FTC refers to as “vigorous enforcement”, of laws already on the books that criminalize turning a profit on of health, location or other sensitive data.
