Command for setting a custom keyboard shortcut
in flag

I am using Ubuntu 20.04 LTS

While typing in Texmaker, if I want my cursor to jump to end of the line, I have to press the end button. which is far in the corner.

So I went to settings-> Keyboard Shortcuts-> Set Custom Shortcut, but it requires a command to get there.

What should I write there to make the shortcut work the same as pressing the end key?

Firefox: Cursor doesn't disappear in fullscreen
us flag

Apologies if this is more of a Firefox forum question but I thought this may be a better place to post the question. Basically, Firefox does not auto hide the cursor when I go into fullscreen mode. I do not have any special extensions installed. I installed the full version of Ubuntu on my PC.

The only way I could get the computer to turn off was to physically press the shutdown or restart button on my tower. Has anyone else experienced this odd behaviour? I wonder if it  ...

Starred files function became broken, can you help me fix it?

I have a problem where I can not STAR any new files or folders in Ubuntu 21.04 until after I reboot. Additionally, any files shown in a 'symlink folder window' cannot be starred, nor do they show as 'Starred' even if the actual file is starred.

This is possibly related to another question RAW Thumbnails in Nautilus (Sony .ARW) where I was attempting to get Raw thumbnails to display. The method th ...

The Stunning Power of Questions

Much of an executive’s workday is spent asking others for information—requesting status updates from a team leader, for example, or questioning a counterpart in a tense negotiation. Yet unlike professionals such as litigators, journalists, and doctors, who are taught how to ask questions as an essential part of their training, few executives think of questioning as a skill that can be honed—or consider how their own answers to questions could make conversations more productive.

That’s a missed opportunity. Questioning is a uniquely powerful tool for unlocking value in organizations: It spurs learning and the exchange of ideas, it fuels innovation and performance improvement, it builds rapport and trust among team members. And it can mitigate business risk by uncovering unforeseen pitfalls and hazards.

For some people, questioning comes easily. Their natural inquisitiveness, emotional intelligence, and ability to read people put the ideal question on the tip of their tongue. But most of us don’t ask enough questions, nor do we pose our inquiries in an optimal way.

The good news is that by asking questions, we naturally improve our emotional intelligence, which in turn makes us better questioners—a virtuous cycle. In this article, we draw on insights from behavioral science research to explore how the way we frame questions and choose to answer our counterparts can influence the outcome of conversations. We offer guidance for choosing the best type, tone, sequence, and framing of questions and for deciding what and how much information to share to reap the most benefit from our interactions, not just for ourselves but for our organizations.
