Command + C does not always work from the first try in Microsoft Word (Office 2011) I have no idea why COMMAND + C doesn't always register from the first time. I sometimes try to copy something off Word, but I have to press COMMAND + C more than once for it to register, otherwise COMMAND + C just prints what was copied in clipboard before. This becomes very irritating.

However I realised that if I press COMMAND then pause for a second, THEN press C, the command always registers.

EDIT

I noticed that when I select any text in word, it takes about a second for the Cut and Copy buttons to be highlighted (otherwise they're greyed out). And THIS has direct effect on this problem. Only when they are not greyed out anymore can I copy and paste using keyboard shortcuts correctly.

What is happening ?
This issue is real and I think every mac user experience it on a weekly basis, but likely people continue to doubt themselves over if they actually command c or not properly.
The fix. If you are using Karabiner like real hacker should:
Just add this to your karabiner complex configurations:
[
    {
        &quot;from&quot;: {
            &quot;key_code&quot;: &quot;c&quot;,
            &quot;modifiers&quot;: {
                &quot;mandatory&quot;: [
                    &quot;left_command&quot;
                ]
            }
        },
        &quot;to&quot;: [
            {
                &quot;key_code&quot;: &quot;c&quot;,
                &quot;modifiers&quot;: [
                    &quot;left_command&quot;
                ]
            },
            {
                &quot;key_code&quot;: &quot;c&quot;,
                &quot;modifiers&quot;: [
                    &quot;left_command&quot;
                ]
            },
            {
                &quot;key_code&quot;: &quot;c&quot;,
                &quot;modifiers&quot;: [
                    &quot;left_command&quot;
                ]
            }
        ],
        &quot;type&quot;: &quot;basic&quot;
    }
]

Now that should make the copy flash a few times in the menu.
You can increase or decrease as much as you want. Personally I have a few more.
