Why do 2019-era email clients [(+/-) a few years] often allow you to delete or enter new destination addresses, but not fully edit them?

Suppose that you are writing an email. You mistype someone’s address in the “To” field. For example, maybe you write, “john.reed@blah.com.” Before sending the email, you remember that that person spells their name in a funny way. You want to delete the letter “H” in “john.” The correct email address is “jon.reed@blah.com”

In a significant number of present-day email clients you cannot edit an email address already entered into the “To” field. Once you press enter or shift the keyboard focus to the body of the email, the “To”-address changes. The user interface changes what you have typed into something which can be deleted/removed, but not edited. This is also true of the carbon-copy fields. If you mistype someone’s email, you have to delete the address completely, and re-type it. For many email clients, left-clicking on the email address might delete it, but it does not enable text editing.

I am talking about the front-end of the interface, not what’s under the hood. What is weird is that in the years from 2000 to 2010, editing a destination email address was trivial. In most email clients, the “To” field was a text-box. You could click anywhere inside of the “To” field and type almost anything you liked. The backspace key worked fine; the delete key worked fine; anything.

Features do not become popular in multiple competing companies user-interfaces, unless those features are an improvement over the old way of doing things. There must be a rationale for disallowing users from editing email addresses previously typed into the “to” field. Technically, you can edit them by deleting and re-typing from scratch, but hopefully my meaning is apparent. What is the thinking behind this? Is it a matter of making “the common case” fast? Which user-cases are faster/easier using the (new or delete) style of design instead of the old (edit text) style of design?

Enter at the end of a specific line

I have the following file.txt that follows the same pattern and I want to modify it where this file is by adding an ip:

# gfhfhgfh gfhfghgfhgfhgfh MACs  # access USER CONSOLA *,!,! /bin/false 

I want to add an ip in the end of the line that contains as patron USER CONSOLE:

 USER CONSOLA *,!,!,!, 

I only manage to add the ip in the whole document at the moment but not in that particular line the code used is

sed 's/\r\?$  /,!' file.txt  

Open folder listing in left pane of Windows Explorer without pressing Enter

Apologies for an obviously stupid question, but I have a problem with Windows 10 explorer I could not find a solution for myself.

When I’m keyboard-navigating the file structure in the left pane of the explorer, the content of folders I go to does not get shown in the right pane. If I want to see it while my cursor is on a particular folder in the left pane, I have to specifically press Enter. Then the content is shown on the right. Otherwise the previous folder listing remains there until I press Enter next time.

Can I force Windows 10 to do that just as it was possible in Windows XP?

Many thanks!

How do I enter recovery mode on an iPhone XS?

I forgot my iPhone’s lock code. I know the iCloud password. I never synced with iTunes. I’m fine with deleting all the content on the device.

I tried following the directions on Apple’s website to enter recovery mode:

  1. Tap Volume up button.
  2. Tap Volume down button.
  3. Press and hold the side button.
  4. This shows me the “slide to power off” slider and a “cancel” button.
  5. Continuing to hold it restarts the iPhone.
  6. The Apple Logo appears.
  7. I continue holding the side button because it states:

    don’t release the buttons when you see the Apple logo, wait until the connect to iTunes screen appears

  8. After the phone is done rebooting, I see a screen that says:

    iPhone is disabled. try again in 15 minutes.

  9. It does not enter recovery mode.

Note: I did try entering the passcode several times a day before and it got disabled for 15 minutes at the longest setting. However, I waited over 12 hours before I tried again, so the 15 minutes should not be a problem. To be sure, I waited another 15 minutes and repeated the whole process to no avail.

I even tried holding all 3 buttons to perform a restart, but this just entered Diagnostics mode, didn’t show up in iTunes, and had no option to enter recovery mode.

No matter what I do, I can’t get iTunes to recognize the device to start the recovery process.

I even tried the steps with an iPhone X where I know the password, but that didn’t enter recovery mode either. I tried with a different iPhone XS and a different computer to no avail either.

Seems like these suggestions from Apple don’t actually work. Any ideas how to enter recovery mode or wipe a phone if you forgot its password?

I’m a flight attendant with dual citizenship of USA and South Korea. Can I enter US using foreign passport?

If I want to use my staff ticket I have to book the ticket under my Korean name (which is completely different from my English name) and Korean passport number. The only thing is I know that for the US you have to enter and leave using your US passport if you’re a citizen. Would it be possible for me to just buy my ticket using my Korean name and passport but when I enter the US just explain my situation and show my US passport to show that I’m a US citizen?

How can I make the user enter 2 inputs and how can I make some calculation on them(i.e adding and subtracting them)?

I trying to create a c program where 2 positive numbers should be taking in and some calculations process should be made on them like( subtract the second one from the first one, adding the 2 numbers)

I am new user of the program and I have never coded before, however, what I have so far is the order of ” Enter two positive numbers”

int main(void) { printf(“Enter two positive numbers:” ); int input; scanf(“%d&input”);
