    Tremors cause accidental double clicks and double letters.


    My hands shake. So, when I click on something, I often get an undesired double click and often accidentally double letters when I'm typing. Is there a way to slow my PC's response to clicks and keystrokes by A VERY SMALL AMOUNT so as to ignore the second impulse?

    I found a way to under Control Panel to add delay, but the shortest delay I can find there is way to long for normal fast typing--I have to pause between correctly repeated letters.

    My sympathies, I have a client with the same familial tremors issues. She now has to set the mouse for left-handed use but no guess how much longer that will last. She also has to type slowly and double-check, not good for her doing in-home office services.

    Your Notebook/Laptop may have a way to turn off the Touchpad to use an external mouse, helps my wife when her thumb accidentally hits it.

    Hate to say it but sometimes a Desktop computer can be "too good" for some purposes.

    Hi folks

    @Newmaven

    @Berton

    One of these things might be OK -- sort of modern equivalent to the old fashioned IBM selectric keyboard -- no speedup on these -- but needs klunky hands (almost Piano player quality).

    https://www.amazon.com/Das-Keyboard-...ct_top?ie=UTF8

    I saw on TV recently a severely disabled guy with restricted hand movement (both hands) using one of these with a headband and a sort of thing like a drumstick -- and very successful.

    Sometimes "Back to the future" is not as bonkers as it always seems to be. !!!

    Cheers

    Thanks for your suggestions.

    I don't quite understand how switching to a laptop would help.

    I'm using a mechanical keyboard already. I guess I should investigate the "anti-ghosting" mentioned on the Das Keyboard link.

    That won't solve the mouse-click problem, though.

    Change the mouse click setting to allow for longer gaps for double clicks.

    Just a comment about the Notebook/Laptop showing in your "My Computers" listing.

    I seem to have found a way to do exactly what you want. It's a little bit involved and needs some caution, though.

    Assuming you are talking about the "Bounce Key" function in Settings > Ease of Access > Keyboard > Use Filter Keys, it is possible to change (further reduce) its value "BounceTime" with Windows' Registry Editor under your user account's key: "Keyboard Response". The "BounceTime" value is given in milliseconds and should be 300, if you picked the smallest option in the Settings user interface (0.3 seconds) and can be modified to 100 (for example). Of course you'd have test to find the proper value that balances between your tremors and your fast typing needs.

    Unfortunately it's a bit tricky and I can't even explain exactly how it's done, because I would need to know your user account's ID in the registry to give you detailed easy to follow instructions. But generally the registry key can be found here:
    Computer\HKEY_USERS\[YOUR USER ACCOUNT SID]\Control Panel\Accessibility\Keyboard Response
    Tricky part is finding your user account SID - you can follow step 4 of this tutorial to get the correct SID: Change Name of User Profile Folder in Windows 10

    Another tricky thing is that Windows Settings seems to like to revert the "BounceTime" back to 300, whenever you change any "Use Filter Key" settings in the normal user interface. So, maybe be prepared to repeat the process a few times until everything is set. Also, after "BounceTime" has been changed manually in the registry, it seems to be necessary to sign out of your account and back in for the change to take effect.

    Windows appears to have three main keyboard response settings that I think are applicable to the OP's issue.

    The first is Bounce, i.e. when you tap a key, how quickly does Windows recognise it?

    The second is Keyboard Repeat Delay, i.e. if you hit the same key again (e.g. as the result of a tremor), how quickly will Windows recognise it (and repeat the keystroke).

    The third is Keyboard Subsequent Repeat Rate, i.e. if you keep hitting the same key, how quickly will Windows recognise it (and repeat the keystroke).

    I think the relevant settings are stored in:

    Code:
    HKEY_CURRENT_USER\Control Panel\Accessibility\Keyboard Response
    Tremors cause accidental double clicks and double letters.-keyboard_response.png

    Why these settings are hidden from the current Win 10 Settings app or Control Panel is beyond me... but I think @Farouk may be on the right track.

    From a very, very quick look and no testing, I cannot think of a reason why any changes would not be dynamic... it's the HKCU (user) hive, not the HKLM (local machine) hive after all.

    Sorry I haven't had time to do any more testing... I'll try to report back, if time allows.

    The OP is talking about both 'mouse click' and keyboard issues due to tremor. There doesn't appear to be the same granularity for mouse clicks in Win 10 (or I'm just looking in the wrong places).

    Unfortunately, Microsoft Support docs for Win 10 only give very generalised info about amending the keyboard but it appears the registry settings refer mainly to milliseconds.

    Note: It's a pain navigating through Start > Settings > Ease of Access > Keyboard (under Interaction in the navigation pane) so if you're doing this a lot it's far easier to create a shortcut on the desktop:

    1. Right-click on a blank area of the desktop and select New > Shortcut.

    2. Enter ms-settings:easeofaccess-keyboard as the 'location' then click on the Next button.
    Tremors cause accidental double clicks and double letters.-create-shortcut.png

    3. Name the shortcut something like Keyboard settings.
    Tremors cause accidental double clicks and double letters.-shortcut-finish.png

    4. Right-click on the newly-created shortcut and choose Properties.

    5. Change the 'Shortcut' key to CTRL+ALT+K then click on the Apply then OK buttons.

    Now using CTRL+ALT+K together will open the Ease of Access centre directly to the Keyboard area.

    Similarly, substituting ms-settings:easeofaccess-mouse at step 2 (and using CTRL+ALT+M) will let you go directly to the Mouse area. (If you use AutoHotkey it's even easier... I have an always-running AHK script and just use WIN+k and WIN+m respectively to open keyboard and mouse settings.)

    Hope this helps...
