access-keys

I want to select all elements that have an accesskey defined on them. I know that i can do this: $('[accesskey]') , but that gives me lot of inputs, hrefs etc, on the page (most of them have an empty accesskey). What is the way to select only the elements where the accesskey actually has a value? Edit: I found the cause of the empty accesskeys as well, was caused by some old disable / restore accesskeys javascript functions over multiple modal dialogs.. normally you won't get that much elements with empty accesskeys With one selector: $('[accesskey][accesskey!=""]').foo How does it work: //

I want to develop a web application, which should (ideally) be fully usable via the keyboard. I know how to handle keyboard events in JavaScript, but managing them for a larger application is quite boring. Is there a library which makes that process easier? Please note that I'm not interested in a full-blown Web GUI framework. I want to keep control over my webpage/application.

I'm trying to read a s3 bucket from Spark and up until today Spark always complain that the request return 403 hadoopConf = spark_context._jsc.hadoopConfiguration() hadoopConf.set("fs.s3a.access.key", "ACCESSKEY") hadoopConf.set("fs.s3a.secret.key", "SECRETKEY") hadoopConf.set("fs.s3a.impl", "org.apache.hadoop.fs.s3a.S3AFileSystem") logs = spark_context.textFile("s3a://mybucket/logs/*) Spark was saying .... Invalid Access key [ACCESSKEY] However with the same ACCESSKEY and SECRETKEY this was working with aws-cli aws s3 ls mybucket/logs/ and in python boto3 this was working resource = boto3

Scenario: Currently I have this XAML code: <Button Content="_Cancel" IsCancel="True" Command="{Binding Path=CancelCommand}" Margin="5"> <Button.ContentTemplate> <DataTemplate> <TextBlock Margin="10,0,10,0" /> </DataTemplate> </Button.ContentTemplate> </Button> Obviously the accesskey (the 'c' key: _Cancel) doesn't work in combination with the TextBlock. I actually think the TextBlock should be a ContentPresenter (below), but this crashes my Visual Studio 2010 instance every time. <ContentPresenter Margin="10,0,10,0" RecognizesAccessKey="True" /> Question: What's the best solution to use
