39 | The cursor moves when selecting text in the current input line, how do I switch this off? |
|
|
40 | See next entry. |
|
|
41 | |
|
|
42 | During rlogin/ssh/telnet/etc. sessions, clicking near the cursor outputs strange escape sequences, how do I fix this? |
|
|
43 | These are caused by the "readline" perl extension. Under normal |
|
|
44 | circumstances, it will move your cursor around when you click into the |
|
|
45 | line that contains it. It tries hard not to do this at the wrong moment, |
|
|
46 | but when running a program that doesn't parse cursor movements or in |
|
|
47 | some cases during rlogin sessions, it fails to detect this properly. |
|
|
48 | |
|
|
49 | You can permamently switch this feature off by disabling the "readline" |
