Hi,
I'm trying to select ranges of amino acid residues using the keyboard so that I can apply sequence features to them. However, there appears to be a number of bugs in keyboard selection of residues in Jalview - unless I am doing something wrong?
I could use the mouse to make selections instead. But, it is much trickier to use the mouse as the "end" residue number is not displayed in the status bar - only the length of the selection. However this length counts gaps in the alignment, giving an inaccurate "end" residue number. When you are working with many sequence features and long sequences this makes mouse selection arduous and time consuming.
So, I try and use the keyboard as follows: switch cursor mode (F2), then enter the first residue (e.g. 25p followed by q) then the last residue (e.g. 378p followed by m). Then right click the selection marquee and apply sequence feature. Works great the first time.
However, the problem is that this only works once. After I do this, a further selection using the keyboard (to create another sequence feature) simply does not work. Also the cursor keys stop working to move the cursor around. Also, the cursor mode cannot be switched back to normal using F2 without reloading the project. This means that between creating every new sequence feature I have to save, close and reload the project.
Unless I am missing something?
Thank you,
Michael
