问题 I am trying to write a program in C on windows command prompt that I can use to practice touch typing. I want to do this by having the program prompt for a letter and as soon as I have entered a letter, I want it to record whether or not that letter was correct and repeat the process a predefined number of times before exiting and telling me my time and accuracy. Making it work by pressing enter between each letter is easy enough, but I feel like it wont be as helpful as it would be if I didn

问题 I would like to send two simultaneous keys such as ALT+S to the sendKeysToActiveElement( function of the R Selenium webdriver. I only see implementations in Java and C. Can this be done? 回答1: Use below code :- String selectAll = Keys.chord(Keys.ALT, "s"); driver.findElement(By.xpath("YOURLOCATOR")).sendKeys(selectAll); Hope it will help you :) 回答2: If you want to send a single keystroke then use: cl$sendKeysToActiveElement(sendKeys = list(key = "tab")) If you press more than two keystrokes

问题 I have a screen with three EditText's, and one of then, the first one, in the top of the screen doesn't call the keyboard when I click on it. I'm not using an AVD, I'm using my own device, and tested in others devices and same result. I'll put the screen here and the xml codes... there is nothing diferent between the EditTexts, just position. To make an input in that EditText I need to select one of the EditText above, and then the keyboard shows up. At least it doesn't hide when I select the

问题 In our app, we set the keyboardAppearance to dark. This produces a black keyboard, as expected. However, if the keyboard is showing, and we press the home button, and then go back into the app, the keyboard turns white, as shown. Any ideas why? 回答1: It may have todo with the fact that the keyboard is a global object. There's only ever one keyboard in memory at any given time. Also, the OS will automatically change the keyboard color based on the background. Therefore, your setting is probably

问题 I recently started learning Vim and before I go deeper I have a question I need answered. Using a AZERTY keyboard, should I remap the keys for the commands and shortcuts to fit the position of the keys of a QWERTY keyboard? I am asking this because obviously quite a lot of thinking must have being put creating thoses commands, and when I see how far the '$' is on a AZERTY keyboard compared to the QWERTY one for example I can't help but think it might feel wrong at some point. Here is the

问题 I'm just noticing that on my laptop (Dell XPS 15z) there's no BREAK key (no dedicated number keypad). I'm running the debugger step-by-step and then when all seems fine, I just let it play out. However, it's running in an infinite loop and now I'm realizing there's no way to stop it without the break key!!!! Is this a bad joke? I had to reboot the computer; is there a more graceful way?? Thanks. 回答1: just press the escape key twice ;-) 回答2: Solution #1 (It works most of the time): When some

问题 I'm trying to find a way to add a key or button to the SwiftUI numberPad. The only references I have found say it is not possible. In the Swift world I added a toolbar with a button to dismiss the keyboard or perform some other function. I would even build a ZStack view with the button on top but I can't find a way to add the numberPad to my own view. All I'm really trying to do in this case is dismiss the numberPad when the data is entered. I first attempted to modify the SceneDelegate to

问题 Like most french users, when I want to go to my terminal home, I have to type cd ~ However, the keyboard requires me to press options + n and then space to disambiguate between me trying to do ñ or ~ for example. Is there a way to overload this behavior, as I almost never want to use the tilde symbol the way spanish people does ? Karabiner looked promising but it won't let you define custom mapping. It requires you to chose between a set of predefined ones, online. 回答1: Ukelele can create a
