Hi Mike Graham,
Thank you for visiting Microsoft Answers.
Is it causing delay only with shift key and ctrl key?
The remote desktop connection is entirely dependent on the connection speed of the network however you may change the connection speed settings, or use fewer visual effects on the remote computer.
- Open Remote Desktop Connection by clicking the Start button, clicking All Programs, clicking Accessories, and then clicking Remote Desktop Connection.
- Click Options, and then click Experience.
- Choose the appropriate connection speed, if necessary.
- Select or clear the check boxes for the visual effects you want to use or show. In general, the fewer effects you select, the faster the connection will be. But selecting Bitmap caching will improve connection speed.
