   - continuous input: if reach either '9' or '0' in a digit position, then it jumps over to the senior digit and decreases/increases it.
   - fast input: if fast encoder rotation is detected, then it increases/decreases ten times of a current digit position
   - **NEW** "Running" frequency - the value of frequency is applied "on a fly" with a small 0.5 sec delay, so that you keep adjusting the frequency by encoder and the value is applied in 0.5 sec after your input is complete.
-- **NEW** - `Stepped Sweep Generator`: the frequency is varied in a range defined by values set in Ch#0 (start of the range) and Ch#1 (end of the range) with signal settings of Ch#0 and discrete steps of 0,1 of a current running frequency (kind of logarithmical steps).
+- **NEW** - `Stepped Sweep Generator`: the frequency is varied in a range defined by values set in Ch#0 (start of the range) and Ch#1 (end of the range) with signal settings of Ch#0 and discrete steps of 0,1 of a current running frequency (kind of logarithmic steps).
 Frequency value steps either up or down from the start of the range depends on what channels' frequency is larger. Frequency is changed discretely every 250 mSec (can be changed at compilation). 
 The running `Stepped Sweep Generator` cycle is indicated by a blinking cursor at the end of a frequency value. Can be activated for Ch#0 only and uses its signal settings. 
 While running, can be cancelled by short press and hold of OK button. When the end of the range is reached, it pauses for 3 sec and switches back to Ch#0 settings.
